$unlink'ing photos

[graham23s]

Hi Guys,

 

what i'm trying to do here is unlink(delete) the previously uploaded photo by the user, before the new one is uploaded, but i'm having trouble with the unlink bit

 

here the code:

 

 

<?php    
  $photo1 = $_FILES["image"]["name"];
  $username = mysql_escape_string($_POST["username"]);
  $max_image_size = 512000; 
  $allowed = array("image/gif","image/jpg","image/png","image/jpeg");
  $max_image_width = 500;
  $max_image_height = 450;
  $random_number = rand(0000,9999);
  
  // The renamed photo...////////////////////////////////////////////////////////////////
  $renamed_photo = $random_number.$_FILES["image"]["name"];   
  
  // Check there wasn't a blank submission...////////////////////////////////////////////
  if(empty($_FILES["image"]["name"])) {
  
       echo "<p>Sorry, But No File Was Selected, Please Go Back And Try Again.</p>";
       exit;  
  }
  
  // Validation for Image...
  if ($_FILES["image"]["size"] > $max_image_size) {
  
   echo "<p>Sorry <b>$username</b> That Image Is Bigger Than The Allowed Size Of 3mb Please <a href=\"java script: history.go(-1)\">Go Back</a></p>";
   exit;
   
  }
  
  #####################################################################
  // Validate image dimensions...////////////////////////////////////////////////////////
  $dim = getimagesize($_FILES["image"]["tmp_name"]);

  if($dim[0] >= $max_image_width || $dim[1] >= $max_image_height) {
  
    echo "<p>Sorry, That Image Isn't Within The Current Upload Dimensions Please Go Back And Upload Another!</p>";
    exit;
    
  }  
  // Validate image types.../////////////////////////////////////////////////////////////
  if (!in_array($_FILES["image"]["type"], $allowed)) {
  
    echo "<p>Sorry, That File Isn't One Of The Allowed File Types Only <b>.gif .jpg & .png</b> Are Allowed.</p>";
    exit;
    
  }  
  #####################################################################
  
  $uploadpath = "uploads/"; // <- Upload folder...
  $uploadpath = $uploadpath.$renamed_photo;

  #####################################################################  
  if (!move_uploaded_file($_FILES["image"]["tmp_name"], $uploadpath)) 
  
     die("<p>Sorry, There Was An Error Uploading Your Image!");
     echo("<p><br />The Image (<b><font color=\"red\">" .$_FILES["image"]["name"]. "</b></font>) Has Been Uploaded Successfully! <a href=\"my_account.php\">Back To My Account</a><br />");
     
    
  // Create our query.../////////////////////////////////////////////////////////////////
  $sql = "UPDATE membership SET photo1='$renamed_photo' WHERE username='$username'";

  // Run our query...////////////////////////////////////////////////////////////////////
  $rs = mysql_query($sql, $conn) or die(mysql_error());
?>

 

cheers

What problem are you having?

Hi Mate,

 

really just how to apply the unlink code and where in the code above to apply it.

 

any tips would be great

above

 if (!move_uploaded_file($_FILES["image"]["tmp_name"], $uploadpath)) 

Youd need to tell us what file you want deleted to show you the exact unlink code.

Hi Mate,

 

it's not really 1 particular image file , it's basically whatever the user uploads as a pic, heres my form code:

 

<form action="upload_photo_done.php" method="POST" enctype="multipart/form-data">
<tr>
<td bgcolor="#E2E2E2">Upload Location:</td><td bgcolor="#E2E2E2" align="left"><input type="file" name="image" size="40"></></td>
<tr>
<td bgcolor="#E2E2E2">Current Uploaded Photo:</td><td bgcolor="#E2E2E2"><?php 
    if($photo != 0) { 
    
     echo "<img src='uploads/no_pic.jpg' />"; 
     
       } else { 
    
     echo "<img src='uploads/$photo1' border='0' />"; 
     }
?></td><td><a href="">Delete</a></td>
<tr>
<td bgcolor="#E2E2E2"> </td><td bgcolor="#E2E2E2"><input type="submit" name="submit" value="Upload Main Photo!"></td>
<input type="hidden" name="username" value="<?php echo $username; ?>" >
<input type="hidden" name="MAX_FILE_SIZE" value="MAX_FILE_SIZE" />
</tr>
</form>

 

cheers
