Re: How can i remove the error from the top of the page?

THank you @broj1, it works. But i had to change this:

if(empty(trim($_POST["title"])) || empty(trim($_POST["author"])) || empty(trim($_POST["content"]))) {

to this:

if(empty($_POST["title"]) || empty($_POST["author"]) || empty($_POST["content"])) {

Because with using trim() i got error.

I read the link you gave me, but could you please explain every line i will point to? I can't understand them wellm need some more clear explanation, thank you.

$sql = "INSERT INTO Posts (Title, Author, Content)

//why you have used : sign before each one? what does it do?
VALUES (:title, :author, :content)";

// what is $stmt for?
// what does bindParam do exactly?
$stmt->bindParam(':Title', $title);
$stmt->bindParam(':Author', $author);
$stmt->bindParam(':Content', $content);
$conn->exec($sql);
} catch(PDOException $e) {

// why you have typed echo $sql in this line?
//what does it echo and print on the page?
//(sql is the variable here that holds an order, the order of inserting data into table, right?
//so the $sql variable has not anything to echo and print, right?
//maybe is misunderstanding for me.

Want to create delete action for CMS posts

Hello.
There is an html table in admin page, with head columns (POST ID | POST TITLE | POST AUTHOR | ACTION).
And in each row, will contain a post id, a post title, a post author that gets from database.
And in the Action column, there is a "delete" word that is a link with href="#" for now.
I want the script when i click on the delete word in each rows, erase that row of data from the table of the database and from the html table.
I don't know how should i do that. Just need guidance to understand what i can do for that, thank you.

Re: How can i remove the error from the top of the page?

What do you mean by this? Sorry my English is not good enough, so i didn't understand what you mean by this:

And for security reasons use prepared statements.

Yes it works. Now when i click the submit button, no blank rows will be added into table and no error appears on the top of the page. Thank you.

But there is an other problem now.
First i login to this page(the page of writting posts) from login.php page by entering username and password, but suddenly after entering to the page of writting posts, the message "You forgot to enter some required data" will appear on the top of the page, but i haven't clicked submit button yet!
How can i fix it? I don't want script to show this message exactly after login to page without any action.

How can i remove the error from the top of the page?

Hi, as you know i'm creating my own CMS.
This is a part of my code:

     if (!empty($_POST["Title"]) && !empty($_POST["Author"]) && !empty($_POST["Content"])) {
         $sql = "INSERT INTO Posts (Title, Author, Content)
         VALUES ('$title', '$author', '$content')";
     }

I want the script to check if Title Field and Author field and Content field are empty, stop sending blank rows into table. Because when i click the submit button while all these fields are empty and then check the table, i see blank rows added into table.

Now with the code above, no blank rows will be added to table but when i click the submit button while all those fields are empty, this error will be appeared on the top of the page suddenly!
General error: trying to execute an empty query
Well, how can i remove that error from the top of the page?!

With this code, all posts in the Posts table will be printed into the page and users can see all post one after another.

Now how can i ask the script to echo only 3 posts in each page?
I think @lps mentioned this limitation in his code, but i didn't understand it clear.

And there must be a "NEXT" button to direct users into next pages to see next 3 posts, correct? So how should i do it? (My code above is in "user-view-page.php" file, so do i need more php pages to show next 3 postes with NEXT button?!)
For now, just need your guidance, thank you.

Re: Problem with getting data fro mtable and echo data

I changed my code to this:

$servername = "localhost";
$dbname = "mydbname";
$dbusername = "mydbusername";
$dbpassword = "mydbpassword";
try {
    $conn = new PDO("mysql:host=$servername;dbname=$dbname", $dbusername, $dbpassword);
    $conn->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);

    $sql = "SELECT Title FROM Posts";
    $result = $conn->query($sql);

    foreach($result as $row) {

        echo "<br>";
    }

} catch(PDOException $e) {
    echo $sql . "<br>" . $e->getMessage();
}
$conn = null;
?>

And the output was all Titles. Is it good or is better to write it in another way?!

And something more... in my Posts table there are some rows that are completely empty (they have been created when i clicked the Submit button on the editing post area without typing any title or author name or any content.)
Now whith the code above, those empty rows will be printed in the output too. I mean sth like this:

First post



my first post here...

Second post
a new post

You can see blank lines between titles that that are printed. How can i tell the script not to print those blank lines?

Re: Problem with my login page, facing with a blank page

The User table has 3 columns, ID, Username and Password.

Well i still need more explanation to understand it well.
These two lines get the password of the $username and put it into $rsult, am i right?! Correct?!

        $sql = "SELECT * FROM Users WHERE Username = '$username";
        $result = $conn->query($sql);

The part you gave me in 5 lines, check to see if the $result value is not empty with count() > 0 correct? And then print the row, will print the password right?

If not please explain your 5 lines code for me, thank you. I want to understand each line exacty and very well.

I thought i should put those 5 lines before my if part and change this if ($password == $result) { to this if ($password == $row) { , but i faced with a blank page. Why? What was the reason.
It seems i didn't understand sql well.

he queried result from the 'Users' table will be all columns as you select all in you query, therefore the comparism in if ($password == $result) { will have to be reviewed again.

I think the reason must be the action= wich is not in the <form> tag. The action sets the Destination where data should be sent to, correct? So here that the Destination is not an other php file, is db table, what can i type for action for the <form> tag?

Re: need help with an error

I replaced the last one with this:

    <?php
    session_start();
    include('includes/functions.php');

And for two other files, i moved the html part into after session_start().

But still i have problem, nothing changed. I can't login into admin area and will get the error to check details, i mean the error message for login form code. But now there is no log_error, so how should i find the problem?

I'm using a tutorial video. I typed all codes exactly like the vido but the result was different. In that video, session_start() was not the first thing on the file, was like what i post in my seccond post here, but there was no problem on the video.

Re: need help with an error

Well, in 2 files, session_start() is not the first thing in the page, is like this:

<html>
<head>
<title>page title</title>
</head>
<body>
<?php
session_start();

And in one other file is like this:

<?php
include('includes/functions.php');
session_start();

And what is BOM?
How can i understand if all files are saved az UTF-8 without BOM or not? What should i do for that?

need help with an error

Hello.
I'm creating a CMS. I've got this log_error.
Can you explain the problem for me if the error message is clear enough for you to understand it? I'm new to PHP.
the log_error says:

PHP Warning: session_start() [<a href='function.session-start'>function.session-start</a>]: Cannot send session cache limiter - headers already sent

Re: how to print every word starts with "A" in a urlpage

Thank you @snippsat. I have 2 questions:

print link['title'] what is title? The alt of the <img> tag?

except KeyError: what does keyError mean here? What the keyword keyError is for?

Re: how to print every word starts with "A" in a urlpage

I want the script to find all the names of singers that starts with the latter "A" in a url page. First i asked my script to check the content of all <il> and <td> tags but now i want to change it.
I want the script to check the url page i gave to it and then find and save all the names of singers on that page that starts with the letter "A". It's my homework and i don't know how to do that. Friends suggest me using dictionary to check words with it to find if they are names of human or not. But the homework asks me not to do that.
So now i want my script to find every word that start with "A" in that url page and print it for me. Then i should find a way to ask my crawle just save those words starting with "A" that are singers names.
Very difficult!!!

Re: how to print every word starts with "A" in a urlpage

Well i changed it into this:

for word in soup.text:
    if word.startswith('A'):
        print word

But now the output is this: (many A letter)

A
A
A
A
A

how to print every word starts with "A" in a urlpage

Hello!
How can ask my scipt to print every word in a url page that starts with the letter "A" in this case?
This is my code:

from bs4 import BeautifulSoup
import urllib2

url = 'http://www.thefamouspeople.com/singers.php'
html = urllib2.urlopen(url).read()
soup = BeautifulSoup(html)
for word in soup.text:
    if soup.text.startswith('A'):
        print soup.text

But it doesn't print anything for output.
