Hello everyone!
I’m having a problem with some pieces of code i found, they’re meant for uploading images, which they do brilliantly except for those images are loaded into a static html-page, which means they should have the same name went they are uploaded through the form
So as an admin you have 10 “boxes” (i don’t know the proper name) for uploading images to a certain page, now if you want for example te replace the second picture you onyl have to insert a picture in the second box. But eversince i’m not able to get the pictures renamed when they upload, the whole system fails
So here is the code.
[php]<?php
//define a maxim size for the uploaded images in Kb
define (“MAX_SIZE”,“1024”);
//This function reads the extension of the file. It is used to determine if the file is an image by checking the extension.
function getExtension($str) {
$i = strrpos($str,".");
if (!$i) { return “”; }
$l = strlen($str) - $i;
$ext = substr($str,$i+1,$l);
return $ext;
}
//This variable is used as a flag. The value is initialized with 0 (meaning no error found)
//and it will be changed to 1 if an errro occures.
//If the error occures the file will not be uploaded.
$errors=0;
//checks if the form has been submitted
if(isset($_POST[‘Submit’]))
{
//reads the name of the file the user submitted for uploading
$image=$_FILES[‘image’][‘value’];
//if it is not empty
if ($image)
{
//get the original name of the file from the clients machine
$filename = stripslashes($_FILES[‘image’][‘value’]);
//get the extension of the file in a lower case format
$extension = getExtension($filename);
$extension = strtolower($extension);
//if it is not a known extension, we will suppose it is an error and will not upload the file,
//otherwise we will do more tests
if (($extension != “jpg”) && ($extension != “jpeg”))
{
//print error message
echo ‘
Unknown extension!
’;$errors=1;
}
else
{
//get the size of the image in bytes
//$_FILES[‘image’][‘tmp_name’] is the temporary filename of the file
//in which the uploaded file was stored on the server
$size=filesize($_FILES[‘image’][‘tmp_name’]);
//compare the size with the maxim size we defined and print error if bigger
if ($size > MAX_SIZE*1024)
{
echo ‘
You have exceeded the size limit!
’;$errors=1;
}
$parts = explode( ‘.’, $imagename );
$extension = strtolower( $parts[‘1’] );
$new_filename = strtolower( $_POST[‘new_filename’] ) . $extension;
//we will give an unique name, for example the time in unix time format
$image_name=time().’.’.$extension;
//the new name will be containing the full path where will be stored (images folder)
$newname= $new_filename;
//we verify if the image has been uploaded, and print error instead
$copied = copy($_FILES[‘image’][‘tmp_name’], $newname);
if (!$copied)
{
echo ‘
Copy unsuccessfull!
’;$errors=1;
}}}}
//If no errors registred, print the success message
if(isset($_POST[‘Submit’]) && !$errors)
{
echo “
File Uploaded Successfully! Try again!
”;}
?>[/php]
And the uploadform
<form enctype="multipart/form-data" action="upload.php" method="post">
Image 1: <input name="userfile[]" type="file" /><br />
Image 2: <input name="userfile[]" type="file" /><br />
Image 3: <input name="userfile[]" type="file" /><br />
Image 4: <input name="userfile[]" type="file" /><br />
Image 5: <input name="userfile[]" type="file" /><br />
Image 6: <input name="userfile[]" type="file" /><br />
Image 7: <input name="userfile[]" type="file" /><br />
Image 8: <input name="userfile[]" type="file" /><br />
Image 9: <input name="userfile[]" type="file" /><br />
Image 10: <input name="userfile[]" type="file" /><br />
<select name="destination">
<option value="1">home</option>
<option value="2">Information</option>
<option value="3">About Us</option>
<option value="4">Sport & Fitness</option>
<option value="5">Exchange Visit</option>
<option value="6">Alcohol, Cigarettes & Drugs</option>
<option value="7">Food & Drinks</option>
</select>
<input type="submit" value="Upload" />
I hope someone can help me!
