Re: archive list (blog style) using php and mysql

I hope I understood OK what you want. I suggest you do it as a single unordered list and use css styling (classes) to handle indent. I am posting an example with code for complete page so you can see what I mean. You can adapt CSS to suit your taste. Note that I removed the GROUP BY clause form the query (otherwise you can not display all the posts).

Re: How to add script :"Are you sure to delete data?"

After looking closer at your code I figured out that you do not need neither javascript nor ajax. Before posting my version of code I have to warn you that deleting records using GET method is a bad practice considering the semantics and security. Make sure only authenticated users can get to this script. Here is the code (take it as a concept):

// connect to the database
include 'Connect.php';

// confirm that the 'student_id' variable has been set
if (isset($_GET['student_id']) && is_numeric($_GET['student_id']))
{
    // if user clicked on a Delete buttton, then delete the record and redirect
    if(isset($_POST['confirm-delete'])) {

        // first remove the delete element form the $_POST
        unset($_POST['confirm-delete']);

        // get the 'student_id' variable from the URL
        $student_id = intval($_GET['student_id']);

        // delete record from database
        if ($stmt = $mysql->prepare("DELETE FROM student_information WHERE student_id = ? LIMIT 1"))
        {
            $stmt->bind_param("i",$student_id);
            $stmt->execute();
            $stmt->close();
            $mysql->close();

            header("Location: Admin_Home.php");
            exit();           
        }
        else
        {
            $mysql->close();
            // if error redirect to the error page
            header("Location: Error.php");
            exit();
        }
    }

    // prompt and a form containing the confirm button
    echo "<p>Do you realy want to delete the record?</p>";
    echo '<form action="#" method="post">';
    echo '<input type="submit" name="confirm-delete" value="Delete">';
    echo '</form>';
}
else
    // if the 'student_id' variable isn't set, redirect the user
{
    header("Location: Admin_Home.php");
}

As you see I used a form with a button and a POST method, so I can first check whether a button was clicked. You should add a cancel button as well and redirect without deleting if pressed.

On line 6 you must enclose the associative index in quotes. Consequently you have to change the code for the query slightly, like:

or:

mysql_query("SELECT LRCard FROM student_information where student_id='{$_GET['id']}'");

print_r($_POST['child-fname']);
print_r($_POST['child-lname']);

Seems like eburlea was right in his first post since there is no $query variable in your script. Try looping over the query object directly:

    $product = $row['product'];
    $price = $row['price'];
    echo "<tr>";

Re: Searching Through Database

You will have to check for values of each of the fields and build the query accordingly. Something like:

$query = "SELECT Schedule.Channel_Number, StationInformation.Station_Name, Schedule.Program_Name, Schedule.Date, Schedule.Time FROM Schedule INNER JOIN StationInformation ON Schedule.Channel_Number=StationInformation.Channel_Number INNER JOIN TVShows ON Schedule.Program_Name=TVShows.Program_Name WHERE 1 ";

If(isset($_POST['date']) && !empty($_POST['date']))  {
    $date = mysql_real_escape_string($_POST['date']);
    $query .= " AND Schedule.Date='$date'";
}

    If(isset($_POST['startime']) && !empty($_POST['startime']))  {
    $startime = mysql_real_escape_string($_POST['startime']);
    $query .=  " AND Schedule.Date='$startime'";
}

etc.

As You can see I also added a bit of security escaping the input. You can enhance it even more. And start thinking of dropping the old mysql extension and maybe start using PDO.

Re: Trouble Setting Session Variable

Yes, I was a bit quick, sory. The thing is you want to use ajax to send a request to another php page which then sends a response which is a html code for a table containing results. You send a ServiceOrders category parameter along to use it as a filter in the query. Maybe the best would be to use the jquery post() method which sends a request along with the parameter and puts the response in the div you wanted. Mind you, the called php page does not have to have all the html stuff (like head tags etc) only the php code querying the database and echoing the html table displaying the results. Also I would use data in a JSON instead of string and I moved the script to the bottom of the html. I tested the code below and it works .

<!DOCTYPE html>

<head>   

<link rel='stylesheet' type='text/css' href='styles.css' />

Re: Trouble Setting Session Variable

Why don't you use the second parameter of the load() function for sending it over to the theServiceOrderReport.php. You basically do not need a session var for that.

First add an ID to the select element:

<select name="ServiceOrders" id="ServiceOrders">

Then read its value and send it over with the load():

$("#refresh").on("click", function() {
    // selected value
    var categoryVal = $("#ServiceOrders").val();
    $("#mydiv").load("http://192.241.175.69/ServiceOrderReport.php", categoryVal);
return false;
})

Read it from the $_POST array and use it in the query (you can also store it in session var here):

$ServiceOrders= $_POST["ServiceOrders"];

Re: how to get rid of these erros ?

Sory for late reply. Obviously $_FILES['userfile'] does not exist. You should place the code that reads the uploaded file information and writes to the database within the if(isset($_POST['upload']) && $_FILES['userfile']['size'] > 0) block. Something like this:

if(isset($_POST['upload']) && $_FILES['userfile']['size'] > 0)
{

    $fileName = $_FILES['userfile']['name'];
    $tmpName = $_FILES['userfile']['tmp_name'];
    $fileSize = $_FILES['userfile']['size'];
    $fileType = $_FILES['userfile']['type'];
    $fp = fopen($tmpName, 'r');
    $content = fread($fp, filesize($tmpName));
    $content = addslashes($content);
    fclose($fp);
    if(!get_magic_quotes_gpc())
    {
        $fileName = addslashes($fileName);
    }
    include 'config.php';
    include 'opendb.php';
    $query = "INSERT INTO upload (name, size, type, content , description ) ".
    "VALUES ('$fileName', '$fileSize', '$fileType', '$content', '$description')";
    mysql_query($query) or die('Error, query failed');
    include 'closedb.php';
    echo "<br>File $fileName uploaded<br>";
?>


 <form action="upload.php" method="post">
 Image Description: <input  type="text" name="imgdesc">
                               <input type="submit" value="submit">
</form>

<?php

$allowed_filetypes = array('.jpg','.jpeg','.png','.gif');
$max_filesize = 1445760;
$description = $_POST['imgdesc'];

$filename = $_FILES['userfile']['name'];
$ext = substr($filename, strpos($filename,'.'), strlen($filename)-1);

if(!in_array($ext,$allowed_filetypes))
  die('The file you attempted to upload is not allowed.');

if(filesize($_FILES['userfile']['tmp_name']) > $max_filesize)
  die('The file you attempted to upload is too large.');



} else {
     echo 'There was an error during the file upload.  Please try again.';
}

This way the file gets inserted into the db only when some data about it exists. You might want to reaarange the code depending on what you actually want to achieve.

Re: mysql explode and insert in mysql

Use explode and implode and form an SQL statement:

$values = explode(' ', "claim for my new mercedes");
$sql = "INSERT INTO mytable VALUES ('" . implode("','", "$values") . "')";

Or use str_replace and form an SQL statement:

$sql = "INSERT INTO mytable VALUES ('" . str_replace(' ', "','", "claim for my new mercedes") . "')";

This works only if you use space as a separator. Note that all values in the query are enclosed in quotes.

Re: PHP search and filter problem

I tested both my suggestions in my environment and they work. But please note, you have an extra space in one of the elements of the $fields array. I also simplified the code since there is no need to have intermediate $wheres array. Also see how I changed the name attributes of the select elements. So this is the code (see also the comments in the code):

<?php
// first check if $_POST is set and not empty
if(isset($_POST) && !empty($_POST)) {

    $fields = array('eventID','eventTitle', 'te_events.venueID', 'te_events.catID', 'eventStartDate', 'eventEndDate', 'eventPrice');

    // start building the query
    $sql = "SELECT eventID, eventTitle, te_events.catID, te_events.venueID, te_category.catDesc, te_venue.venueName, te_venue.location,  eventStartDate, eventEndDate, eventPrice 
    FROM te_events INNER JOIN te_category ON te_category.catID=te_events.catID 
    INNER JOIN te_venue ON te_venue.venueID=te_events.venueID
    WHERE 1";

    // loop through the POSTed array,
    // and add WHERE clauses to the query
    foreach ($_POST as $key => $val) {

        // check if the $_POST key (form field name) exists in the $fields array
        // and has allowed value
        if(in_array($key, $fields) && ($val != '' && $val != 'Select')) {

            $sql .= " AND $key='$val'";
        }
    }

    // add sorting to the query
    $sql .=  " ORDER BY eventTitle";

    // DEBUG: display the query
    echo $sql;
}

?>
<form action="#" method="post">

Re: PHP search and filter problem

Yet another approach. Do not use table name in the array:

$fields=array('eventID','eventTitle','venueID','catID ',
'eventStartDate','eventEndDate','eventPrice');

Prepend table name to all $wheres:

// add to array of WHERE clauses only if value is not FALSE
if (${$field}) { $wheres[]="$field='" . 'te_events.' . ${$field}."'"; }

Again, not very flexible (and I am not sure if this is correct since I do not know all the logic).

Re: PHP search and filter problem

Depends on the situation. So the venueID and catID are from another table. You could code it this way:

...

  // add to array of WHERE clauses only if value is not FALSE
  if (${$field}) { 
      $wheres[] $field = venueID || $field = catID ? "$field='" . 'te_events.' . ${$field}."'" : "$field='" . ${$field}."'"; 
  }
}
...

The above code checks if the fields need to be prepended with the table name. But this code is not very flexible. Other approach would be to have select names contain table names (with dots) but I am not sure if this is valid in HTML:

<select class="select" name="te_events.catID" id ='catID'>

Re: dynamically increase the width and height of the div

Typically you would load all three divs with images of different size. One of the divs will be displayed while the other two will not. You use display:block for displayed div and display:none property for the two other divs:

<div id="large" style="display:none"><img...
<div id="medium" style="display:block"><img...
<div id="small" style="display:block"><img...

or appropriate class. Now when user clicks on radio buttons you use javascript or jquery to change the display property of the divs as apprpriate:

$('#large').show();
$('#medium').hide();
$('#small').hide();

If there are many images on the page you might want to use ajax instead of preloading them.

Re: Dynamically Create a Form

Describe your tables in a way that you can create forms and generate queries. A simple way of doing it would be to have table fields stored in an associative array where keys would be field names and values would be field types. That way you can tell whether to use nput field or textarea in the form.

$table = array(
    'tablename' => 'table1',
    'filed11' => 'varchar',
    'field12' => 'smallint',
    'field13' => 'text',
)


$table2 = array(
    'filed21' => 'integer',
    'field22' => 'smalint',
)

// form for the selected table (i.e.table1)
echo "<form>";
foreach($table1 as $key => $value) {
    if($key == 'tablename') {
        echo "<input type=\"hidden\" value=\"$value\">";
    } else {
        switch($value) {
            case 'varchar':
            case 'smallint':
                echo "<input type=\"text\" name=\"$key\">"; break;
            case 'text':
                echo "<textarea name=\"$key\"></textarea>"; break;
        }
    }
}
echo '<input type="submit" name="submit" value="Insert data">';
echo "</form>";

// this is how you process the form
if(isset($_POST['submit'])) {
    unset($_POST['submit']);
    $tablename = mysqli_real_escape_string($_POST['tablename']);
    unset($_POST['tablename']);

    foreach($_POST as $fieldname => $fieldvalue) {
        $fieldNamesArray[] = mysqli_real_escape_string($fieldname);
        $fieldValuesArray[] = mysqli_real_escape_string($fieldvalue);
    }

    $query = "INSERT INTO $tablename ("`. implode('` ,`', $fieldNamesArray) "`) VALUES (" . implode("','", $fieldValuesArray) . "')";

    // then execute the query
    ...
}

This is just a concept. It can be much improved but you get the idea.

Re: jquery filters with checkbox

Could you be more specific. Would you like to find all the checkboxes that are clicked? That is easy to implement with the checked selector.

Re: exporting pchart images to pdf

Use one of the PDF libraries out there. I use tcpdf and am very happy with it. Find a function in your pdf library that deals with images. In tcpdf it is the Image() function (see an example here). You can either save the generated image to disk and use it in the Image() function or send the Image() function a base64 encoded string representing the image.

Re: Cannot send session cookie

After I download it offline to run it in my localhost, that error start appearing.

What do you mean by that? You can not download PHP code from a web page, can you?

Anyway, the error you are getting means that you are sending some HTML output before the session_start function. You can not do that since session_start sends a cookie and cookies are a part of a header. And header directives have to be sent before any HTML output. This includes any spaces that maybe you do not see in your code, as well as included files that also should not send HTML before headers. The solution is to put the session_start function on the very beginning of the code (as it says in the comment).

Re: Send Email Function

Nice little function for sending mail if you do not want to be bothered with the details about coding the neccesary mail commands. I haven't tested it but it looks clean and tidy.
