[SOLVED] delete multiple files

[steviez]

Hi,

 

On my site i need to delete multiple files at once, the files would be selected by a check box and then you would hit delete. How would i make php handle this?

Loop through the check boxes checked and use unlink on whatever file it should remove.

[steviez]

how would i do the looping? im quite new to php

[Ken2k7]

Well give your check boxes an array name like 'remove[]'

 

Then when the form is submitted, use $_POST['remove'] to get all the values of all check boxes selected. Then loop through the $_POST['remove'] array.

 

If you're having trouble already, learn PHP first. Best advice I can give.

thanks for that, im currently trying to learn php thats why i need help.

 

I have done what you said and when i use the print_r function i get this:

 

Array ( [0] => on [1] => on [2] => on [3] => on [4] => on [5] => on ) 

 

how do i make it so i can delete my files from that?

 

thanks

Woah.. can you post the HTML form?

[steviez]

Woah.. can you post the HTML form?

 

I have fixed that part now, its the while im stuck on...

 

 

does it go like this?

 

while($_POST['delete'])
{
  // do stuff here
}

No, that would be an infinite loop. Ever used foreach?

[steviez]

No, that would be an infinite loop. Ever used foreach?

 

something like this?

 

$arr = array(1, 2, 3, 4);
foreach ($arr as &$value) {
    $value = $value * 2;
}

 

 

[Ken2k7]

Yup, but you don't need the reference next to $value.

[steviez]

Yup, but you don't need the reference next to $value.

 

this is my code so far and it wont work:

 

<?php
## Delete multiple file ##
if(isset($_POST['file_option']) && $_POST['file_option'] == 'delete')
{
    // Get file path and file id
    $path = $setting['upload_path'];


// Loop through data and delete files
$files_array = array($_POST['delete']);
    foreach ($files_array as $files) 
{
    // Query database to get file info
    $query_file = @mysql_query("SELECT * FROM uploads WHERE id = '".$files."' 
                                                      AND upload_owner = '".$_SESSION['userid']."' LIMIT 1");
	$file = @mysql_fetch_array($query_file);

	// Delete file from server
    @unlink($path.$file['image_name']);

	// Delete thumb from server
    @unlink($path.$file['image_thumb']);

	// Delete file from database
    @mysql_query("DELETE FROM uploads WHERE id = '".$files."' AND upload_owner = '".$_SESSION['userid']."' LIMIT 1");

    // Redirect
    @header("Location:" . $url->url_base . '/myfiles');
}
}
?>

 

any ideas?

What's the HTML form? Also debug stuff, can you echo $path?

What's the HTML form? Also debug stuff, can you echo $path?

 

<div class="right_side" id="right_side">
    <form method="post" action="{$url->url_base}/myfiles" name="file_options">
    <div class="file_options">
      <select name="file_option">
        <option value="" selected="selected">-- Selected Image Options --</option>
	<option value="delete">Delete image(s)</option>
	<option value="">-- Move Image To --</option>
	<option value="1">folder one</option>
      </select>
      <input type="submit" value="Go" />
      <input type="button" value="Upload" />
      <div style="margin-top:8px;"><strong>Select:</strong> <a href="javascript:;" onclick="javascript:selectToggle(true, 'file_options');">All</a>, <a href="javascript:;" onclick="javascript:selectToggle(false, 'file_options');">None</a></div>
 </div>

{if $num_results == 0}
<div align="center" style="margin-top:10px;">
     <div class="info">
 You currently have no uploaded images. 
 </div>
 </div>

 {else}
 <style type="text/css">{literal}
 input.cb {position:absolute; margin-top:4px;}

Your form doesn't even have name attribute for delete. Exactly, how does your code supposed to work. I have no idea what that HTML form is doing with that PHP code. They're like 2 different things.

fixed it! the form was 100% fine it was the following php code:

 

$files_array = array($_POST['delete_file']);

 

should be

 

$files_array = $_POST['delete_file'];

 

all fixed now thanks for your help.
