you can have one table for storing user_id and post_id. When user vote any post there will be entry in that table and if there is any entry vote up-down arrow will not be shown for that post.
Below is logic which i am using. - there is one table having fead url along with last feed date. - second table is feeded data along with inserted date.
So when you want to show feed data check last feed date in first date if it is today's date then you can directly use second table to display data.
But if last feed date is tomorow then you need to parse that feed url and save all data in second table and display from second table.
Simplest way to debug is take your output query and run in phpmyadmin, you will get some idea of error.
$query = "INSERT INTO *********** (time, ad1) VALUES ('$FileName','$topnow')";
mysql_query($query) or die('Error, insert query failed.<br />Run this query in phpmyadmin:'.$query);
session_start(); must be on top of page. i.e. there should not any echo ot HTML code above session_start(); function. And php code should be also at top and then html form, tables. Its not necessary but its a good practice. You forget to add action=" in form.
I have checked some available functions for error handling in php. But i didn't reach to goal.
I want any php error to be shown on custom page. e.g. if there is comma missing and system throw Parse error: syntax error, unexpected T_VARIABLE on the browser, can i create one error.php in proper design and show error message there. Please guide friends.
if $location = mypic.jpg and you have store that image under some directory. e.g. under 'project' folder you have saved image in upload/avatar/mypic.jpg Then <img src="<?='upload/avatar/'.$location?>"> // if your page is beside upload folder. This is relative path.
You want to show image on profile page or message page? You have written image code.What is the problem? echo "<img src='$location' width='100' height='100'>"; For src you have to give either relative path to image or absolute path.
@ardav: I have made one file and one directory hidden by right click and changing property to hidden. And used exec to read file/folder attributes in PHP as shown in above post.. exec('attrib '.$path)
Ohh.. i have checked only for hidden folder. Below is the complete code for files and folder both. I have checked in win7 and its working. Try in your PC.
<?php
function getDirectoryList ($directory)
{
// create an array to hold directory list
$results = array();
// create a handler for the directory
$handler = opendir($directory);
// open directory and walk through the filenames
while ($file = readdir($handler)) {
// if file isn't this directory or its parent, add it to the results
if ($file != "." && $file != "..") {
$str = $directory.'\\'.$file;
$out = trim(exec('attrib '.$str));
$ar = explode($directory,$out);
$temp = explode(' ',trim($ar[0]));
if(!in_array('H',$temp))
$results[] = $file;
}
}
// tidy up: close the handler
closedir($handler);
// done!
return $results;
}
$array_1=getDirectoryList("C:\wamp\www\\test"); // add your path here
foreach($array_1 as $value)
{
echo "<br/>".$value;
}
?>
This code works in windows. I have used exec function to run attrib command to check type of file. In linux os attrib won't work.
<?php
function getDirectoryList ($directory)
{
// create an array to hold directory list
$results = array();
// create a handler for the directory
$handler = opendir($directory);
// open directory and walk through the filenames
while ($file = readdir($handler)) {
// if file isn't this directory or its parent, add it to the results
if ($file != "." && $file != "..") {
$str = $directory.'\\'.$file;
$out = trim(exec('attrib '.$str));
$start = substr($out,0,1);
if($start != 'H')
$results[] = $file;
}
}
// tidy up: close the handler
closedir($handler);
// done!
return $results;
}
$array_1=getDirectoryList("C:\wamp\www\\test");
foreach($array_1 as $value)
{
echo "<br/>".$value;
}
?>
