PHP - Delete File

Hello everyone,

This is my first post and I need a little help. My knowledge of php is limited, so this question may look simple. English isn't my mother tongue, which you have probably noticed already.

So, my problem:
I 've made a a phpscript that adds text to a txt-file, that works perfect, but I also need something to delete some parts of the file.


part of my html-code: Code: [Select]
<form method="POST" action="verwijderscript.php">
<table class="noborder">
<tr><td class="noborder">

<input type="text" id="verwijdertitel" name="verwijdertitel" size="40">
<input type="submit" name="s1" value="Verwijder Bericht" />

</td></tr>
</table>
</form>
part of my txt-file:
Code: [Select]
<div  id="Testtitel">
<span class="subtitel">Testtitel</span>
<span class="rechts">Gepost op 15/03/2011</span>
<br>
<img class="nieuws" src="image.gif"><br>
texttexttexttexttext<br>
texttexttext<br>
text

<div class="streep"></div>
</div id="Testtitel">

<div  id="Testtitel2">
<span class="subtitel">Testtitel2</span>
<span class="rechts">Gepost op 15/03/2011</span>
<br>
<img class="nieuws" src="image2.gif"><br>
texttexttexttexttext<br>
texttexttext<br>
text

<div class="streep"></div>
</div id="Testtitel2">
part of my php-code:
Code: [Select]
<?php

$titel = $_POST['verwijdertitel'];
$oud = file_get_contents("data.txt");
$data = fopen("data.txt", "w+");
$nieuw =  str_replace("id=\""$titel, "id=\"hidden", $oud);


fwrite($data, "$nieuw");
fclose($data);
            header("refresh:0;url=http://www.test.com");

?>

css:
Code: [Select]
#hidden{display:none;}
Problem: parse error line 6 of php-file
And I don't think this works if the error is solved. I don't have a MySQL database, that's why I use a txt files.

What I try to do is to hide the div, it would be better to delete it, but than I need to work with regex, I guess 

Hi!

What i can't figure out, is how to delete between 2 given strings in another file.

Explanation:
I have a file, it contains following:
Code: [Select]
### Start of content 0 ###
Some
Radom
Lines with text 1
### End of content 0 ###

### Start of content 1 ###
Some
Radom
Lines with text 2
### End of content 1 ###

### Start of content 2 ###
Some
Radom
Lines with text 3
### End of content 2 ###
And so on, now i need code, which can find line i give and delete between.

Something like this:

If, i give string:
Code: [Select]
### Start of content 0 ###

Then it will delete this line to the

Code: [Select]
### End of content 0 ###

Hope you can help!

All the best:

I want to delete a file, I'm using Windows XP, however, it gives me Permission Denied:

Code: [Select]
$file =$row['img'] ;
$filedel = "mages/".$file;
unlink ($filedel);
Is the code wrong? I tried setting permission to the folder but in vain...

I am trying to delete a file via unlink(). It's a .html file, stored in a folder on its own.

// current directory
$dir = dirname(__FILE__);
$dir = str_replace('classes','',$dir);
$file = str_replace('./',$dir,$fr['location']);
unlink($fr['location']);
if(!unlink($file)){
echo 'err';
}
if(file_exists($file)){
echo 'ok1';
}

The $fr['location'] stores the real location, as ./uploads/1303577497/barebones.html.

I've tried every combination I can think of to delete it. I've even deleted it from FTP and re-uploaded it, in case it was a permissions issue, but it refuses to go. When I file_get_contents it, it appears as existing.

Can anyone help?

Hello, I'm requesting your help here cause I'm really confused.
I'm looking for deleting entries when an image doesn't load on my links test.

I got all my links in a .txt file like this :
links.txt =
Code: [Select]
<div class="gallery">
 <a href="http://www.website.com/page">
  <img src="http://tc16.easythumbhost.com/image.jpg" onerror="ImgError(this)"/>
 </a>
</div>
#enddiv
the "onerror" code in img src sends an "Image Missing" pic.
What I'd want is to change the "onerror" function to open a php script which deletes all the lines of the div.
This is the script I use to show the links on my page :
Code: [Select]
$links = "links.txt";
 $fd = fopen ($links, "r");
 $content = fread ($fd,filesize ($links));
 fclose ($fd);
 $delimiter = "#enddiv";
 $splitcontent = explode($delimiter, $content);
 $output = array_slice($splitcontent, 0,100);

 foreach ( $output as $divs )
{
 echo "$divs";
}
I've searched hours and tried lots of codes before posting
Help would be very appreciated. Thanks.

I've created a demo page for my CMS, and I want to delete itself and make a fresh content install.

I got the delete part figured out, but what about uploading fresh content files? (only a few text files).

Here's the delete part:

Code: [Select]
<?php
$expiretime=720; // minutes (in how many minutes it deletes the files)

$tmpFolder="tmp/"; // where to delete the files - be careful with this.
$fileTypes="*.*";

foreach (glob($tmpFolder . $fileTypes) as $Filename) {

$FileCreationTime = filectime($Filename);
$FileAge = time() - $FileCreationTime; 

if ($FileAge > ($expiretime * 60)){

//deleting files:
unlink($Filename);
}

}
?>

I have a download-list, and want to have a delete-button/link at each file. I have tried different codes, but i'm new to php and need some help.

if ($handle = opendir('files/engelsk/')) {
               while (false !== ($file = readdir($handle)))
                  {
                      if ($file != "." && $file != "..")
                  {
                        $en .= '&raquo; <a href="/files/engelsk/'.$file.'">'.$file.'</a>&nbsp;&nbsp;-&nbsp;<i><a href="#">Delete file</a></i><br />';
                      }
                   }
              closedir($handle);
              }

It's the "<a href="#">Delete file</a>" I want to be the delete-button.

Please help!

I want to add text to a file, getting it printed out in index.php and later want to edit/delete per row. I give codes page wise. first the form to take data:
add.php:
Code: [Select]
<?php
?>
<form method="post" action="add_data.php">
<fieldset>
<legend>Student List</legend>
Name : <input type="text" name="uname" /><br>
Content : <input type="text" name="age" />
<br>
<input type="submit" name="submit" value="send" />
</fieldset>
</form>
Next adding text to a file: add_data.php:
Code: [Select]
<?php
$id = 1;
if (file_exists("data.txt"))
{
$fp = fopen("data.txt", 'r');
$str = fread($fp, filesize("data.txt"));
$str_arr = explode("|", $str);
foreach ($str_arr as $rec)
{
if ($rec)
{
$id++;
}
}
}

$mode = (file_exists("data.txt"))? "a" : "w";

$fp = fopen("data.txt", $mode);
$line = $id . "--" . $_POST['uname'] . "--" . $_POST['age'] . "|";
$res = fwrite($fp, $line);
fclose($fp);

header("location:index.php");


?>In the index.php, I'd like to fetch data and edit them per row:
Code: [Select]
<?php
$fp = fopen("data.txt", 'r');
$str = fread($fp, filesize("data.txt"));
$str_arr = explode("|", $str);
echo "<table border='1'>";
echo "<tr><td>ID</td><td>Name</td><td>Age</td><td>Option</td></tr>";

foreach ($str_arr as $rec)
{
if ($rec)
{
$rec_arr = explode("--", $rec);
echo "<tr>";
foreach ($rec_arr as $col)
{
echo "<td>$col</td>";
}
print "<td><a href=\"edit.php?id=$id\">Edit</a>/<a href=\"delete.php?id=$id\">Delete</a></td></tr>";
}
}
echo "</table>";

echo "<a href=\"add.php\">Add Data</a>";

?>


Next I want to Edit per row: edit.php:
Code: [Select]
<?php

$fp = fopen("data.txt", 'r');
$str = fread($fp, filesize("data.txt"));
$str_arr = explode("|", $str);

foreach ($str_arr as $rec)
{
if ($rec)
{
$rec_arr = explode("--", $rec);
$id = $rec_arr[0];
$name = $rec_arr[1];
$age = $rec_arr[2];
if ($id == $_REQUEST["id"])
{
echo "<form action='edit_data.php' method='post'>";
echo "Name :<input type='text' name='uname' value='$name' /><br>";
echo "Age: <input type='text' name='age' value=$age /><br>";
echo "<input type='hidden' name='uid' value=$id />";
echo "<input type='submit' value='Edit'>";
echo "</form>";
}
}
}


?>
From edit.php to edit_data.php where I practically try to edit per row:
Code: [Select]
<?php

$fp = fopen("data.txt", 'r');
$str = fread($fp, filesize("data.txt"));
$str_arr = explode("|", $str);

foreach ($str_arr as $rec)
{
if ($rec)
{
$rec_arr = explode("--", $rec);
$id = $rec_arr[0];
$name = $rec_arr[1];
$age = $rec_arr[2];

if ($id == $_POST['uid'])
{
$new_str = $id . "--" . $_POST['uname'] . "--" . $_POST['age'] . "|";
}
else 
{
$new_str = $id . "--" . $name . "--" . $age . "|"; 
}
}
}

fclose($fp);

$fp = fopen("data.txt", 'w');
fwrite($fp, $new_str);
fclose($fp);


?>
The mechanism is simple. Taking datas from a form, explode them to an array and get them into col/row pattern to edit and delete them. But my problem is when I want to edit in index.php page, specially in this part:
Code: [Select]
print "<td><a href=\"edit.php?id=$id\">Edit</a>
It says, undefined index. But I try to catch this $id in the edit.php page, in this manner, as you see in my code:
Code: [Select]
foreach ($str_arr as $rec)
{
if ($rec)
{
$rec_arr = explode("--", $rec);
$id = $rec_arr[0];
$name = $rec_arr[1];
$age = $rec_arr[2];
if ($id == $_REQUEST["id"])
{
echo "<form action='edit_data.php' method='post'>";
echo "Name :<input type='text' name='uname' value='$name' /><br>";
echo "Age: <input type='text' name='age' value=$age /><br>";
echo "<input type='hidden' name='uid' value=$id />";
echo "<input type='submit' value='Edit'>";
echo "</form>";
}
}
}
Have I done any mistake here? If anyone points out, I'll be obliged.

Hello all.  In lack of better terms, I am a programming noobie when it comes to designing code.  I can look at a code and figure it out, but basically I am trying to figure this out.  I host a website from home, running on a server 2008 machine, with apache/php, basically to share files from home, work, friends house, wherever I need.  I do have a FTP for this, but I also want to be able to upload files via http.  I actually want to be able to set a time or date that the file will auto-delete.  Such as, I select a file from my local machine, set the deletion time to 1 hour/60 minutes/3600 seconds, whatever, upload it to the site, and it spit back a url that I can access that file for that set amount of time.  It would be great to implement something like bit.ly to shorten the link, or even something to randomize the link.  Any ideas on that from anyone?  Willing to donate (paypal) a little bit if someone can actually help me out, or point me in the right direction.  A week on google has proved useless. 
Thanks so much.

Extremely new here and to PHP and I have exhausted my newbie resources and my brain on this one.

I understand the 'concept' but am unable to grasp the code! I have tried many snippets and really need help.

Hey all need some help with the subject title.

Have a user text file with all information(Name, address, passwords, etc..) Need to be able to select the user based on Checkbox selection then hit delete button and all users checked will be removed from the txt file and thus removed from HTML page. Im using PHP to show contents of the txt file into my HTML page.

So far i have:


<?php
                  $file = fopen("user.txt","r");
                     
                  echo '<table border="0" width="100%">
                     <tr>
                     <th>Select</th>
                     <th>Username</th>
                     <th>Password</th>
                     <th>FirstName</th>
                     <th>LastName</th>
                     <th>Email</th>
                     <th>Address</th>
                     </tr>
                  ';
                  while(!feof($file)) {
                     $user = explode(":", fgets($file));
                        
                     echo '<tr>
                        <td><input type="checkbox" name="chkDelete" id = "chkDelete" value="select" /></td>
                        <td>' . $user[0] . '</td>
                        <td>' . $user[1] . '</td>
                        <td>' . $user[2] . '</td>
                        <td>' . $user[3] . '</td>
                        <td>' . $user[4] . '</td>
                        <td>' . $user[5] . '</td>
                     </tr>';
            
                  echo '</table>';
                  fclose($file);
               ?>

Am unsure as to how i would go about doing this, help would be greatly appreciated!

Thanks in advanced,

Daniel.

Hi,   I wish to find out is there any possible that I can delete some data inside my php website but inside my sql database, the record will still at there?   Thank you.

Code: [Select]
<?php $page_title = "Central Valley LLC | Photo Addition" ?>
<?php include("header.php"); ?>
<?php include("nav.html"); ?>
<div id="content">
<form action="delprod.php" method="post" enctype="multipart/form-data">
<label for="which">Choose A Product To Remove:</label>
<?php $con = mysql_connect("localhost","phoenixi_cv","centraladmin");
if (!$con)
{
die('Could not connect: ' . mysql_error());
}
mysql_select_db("phoenixi_cvproducts", $con);
$result = mysql_query("SELECT * FROM Products");
echo "<select name=\"which\">";
while($row = mysql_fetch_array($result))
   {
echo "<option ";
echo "value=\"" . $row['id'] . "\">";

if (!$con)
{
die('Could not connect: ' . mysql_error());
}
mysql_select_db("phoenixi_cvproducts", $con);
