    using unlink to delete a file

    in PHP Coding Help

    Posted

    Right i have made a new php file to delete the image but it keeps coming up 'Warning: unlink() [function.unlink]: http does not allow unlinking in /home/a2820511/public_html/testing/image-deleted.php on line 9'

    This is how i have done it....

     

    Table file

      <?php
while($rows=mysql_fetch_array($result)){ // Start looping table row 
?>
  <tr>
    <td class="some-shit"><? echo $rows['id']; ?></td>
    <td class="some-shit"><a href="<? echo $rows['name']; ?>"><? echo $rows['name']; ?></a><br /></td>
    <td align="center" ><? echo $rows['type']; ?></td>
    <td align="center" ><? echo $rows['size']; ?></td>
    <td align="center" ><a href="image-deleted.php?id=<? echo $rows['name'] ?>"><img src="LAS/images/icons/admin/hds/delete.jpg" alt="" width="19" height="19" border="0" /></a></td>
  </tr>
  <?php
// Exit looping and close connection 
}
mysql_close();
?>

     

    Delete image file

    <?php 
$imageDir=$_GET["id"];
unlink($imageDir);
?>
<script language="text/javascript">
window.location ="delete-image.php";
</script>

    I would like to have more of a understanding of this upload file script if any one would like to be a pal and explain whats going on step by step, thats if it's not to much to ask of course :P.

     

    <?php
                /* checking the file extension*/
                if ((($_FILES["file"]["type"] == "image/gif")
                || ($_FILES["file"]["type"] == "image/jpeg")
                || ($_FILES["file"]["type"] == "image/png")))
{
                /* this code will be executed if the file extension matches they above (gif,jpeg,png)*\
  		if ($_FILES["file"]["error"] > 0) /*if more than 0 errors occur the following code will be executed*/ 
                                    {
                                      /* return code (string), $_FILES...(file var)*/
                                          echo "Return Code: " . $_FILES["file"]["error"] . "<br />";
   				 }
  else  {
                   /*listing file details, name, file type, file size*/
                  echo "Upload: " . $_FILES["file"]["name"] . "<br />";
                  echo "Type: " . $_FILES["file"]["type"] . "<br />";
                  echo "Size: " . ($_FILES["file"]["size"] / 1024) . " Kb<br />";
                  /*temp file location*/
                  echo "Temp file: " . $_FILES["file"]["tmp_name"] . "<br />";
                  if (file_exists("upload/" . $_FILES["file"]["name"]))
                                {
                                       /* if there is a file already existing  with the same name as the current file in a procedure then the following code will be executed*/
                                       echo $_FILES["file"]["name"] . " already exists. ";
                         }
  else    {
                  /*moving the successfully uploaded file to the a designated location, in this case upload/.*/
                  move_uploaded_file($_FILES["file"]["tmp_name"],
                  "upload/" . $_FILES["file"]["name"]);
                  echo "Stored in: " . "upload/" . $_FILES["file"]["name"];
             }
       }
  }
else   {
          /*this section refers from the first if statement, if the file extension didn’t match the files listed at the beginning of this script then the following code will be executed.*/
             echo "Invalid file extention”
}
?>
