Hi guys,

I have a basic image upload script (see code below).

The script works well but I would like to add a text box in the script so that the person uploading the photo can give the photo a meaningful name and be easily found on the server.

Any ideas how I could go about doing this as I'm struggling?

Thanks,

Mark

<strong>Notes:</strong><br />
The image will not be resized to this exact size; it will be scalled down so that neider width or height is larger than specified.<br />
When uploading this script make sure you have a directory called &quot;image_files&quot; next to it and make that directory writable, permissions 777.<br />
After you uploaded images and made tests on our server please <a href="delete_all_images.php">delete all uploaded images </a> :)<br />

<input name="submitted_form" type="hidden" id="submitted_form" value="image_upload_form" />

Add a text input to your submit form to take the description, then either save it onto a file for later retrieval, or keep a database with links to the images and store the related descriptions there.

What part are you having trouble with?

I would do the same as vacunita.
Add a text input to your form and name it description.
Then just post that field to your database.

The following is an excerpt from a script allowing multiple upload in one shot
it's up to you to adapt but it is related to what evreyone mentionned ... no big deal, really!

Code: 
//////////// Check Caption size ///////////////////

$img_caption=$_POST['img_caption'];	//$a=implode("<br>",$img_caption); echo"$a";
$counter=0;
		while($counter <count($img_caption) )
			{
			if(strlen($img_caption[$counter])>45 )
					{
	        echo"<b>The Caption <p>$img_caption<br>[$counter]
	        <p>should only contain 45 characters with or without space</b><br>
	        <a href=\"xxxxxx.php?dir_name=$dir_name\">
          <b>Please, try again</b></a>";
          exit();
					}
			$counter++;
			}
//////////// Check caption text ////////////////////			
$img_caption=$_POST['img_caption'];	//$a=implode("<br>",$img_caption); //echo"$a";
$counter=0;
		while($counter <count($img_caption) )
			{
			if (!preg_match("/^[A-Za-z0-9\ ]+$/",$img_caption[$counter]))
					{
	         echo "<h3> The Caption <p>$img_caption<br>[$counter]
	         <p>may only contain alphanumerical characters with or without space.<br></h3>
	         <a href=\"xxxxx.php?dir_name=$dir_name\">
           <b>Please, Go back and enter a Caption</b></a><p>";
           exit();
					}
////////// text OK /////////////////////////////////////
					
/////////// Check if similar caption exists ////////////
$conn=db_connect();

	$result = mysql_query("SELECT img_caption 
	FROM (your table)
	WHERE 
	img_gal='$dir_name'
	AND
	img_caption='$img_caption[$counter]'
	 ");
	$num = mysql_num_rows($result); //echo"$num";
			if ($num >0)
			{
				$cap=implode("<br>",$img_caption);
				echo "<h3> The Caption: --> <p>$cap<br>
	         <p>Was previously posted.<br></h3>
	         <a href=\"xxxxx.php?dir_name=$dir_name\">
           <h4>Please, Go back and enter a UNIQUE Caption</h4></a><p>";
           exit();
					}
