Getting the value of a hidden input with PHP

ralston3

Here is my input on the index.php page:

<form action='liked_button.php' action='GET'>
          <input type='hidden' class='hidden_image' name='hidden_image' value='<?php echo $image_info; ?>' >

So how can I get that $image_info value to show in my liked_button.php?

 $_GET['hidden_image'];

Doesn't work and I have no idea what else to try.

Any ideas?

edited code for that index.php:

<form action='liked_button.php' action='GET'>
<input type='hidden' class='hidden_image' name='hidden_image' value='<?php echo $image_info; ?>' >

When I click the submit button for that form, this is what shows up in my URL:

http://localhost/splindr_2.0/liked_button.php?like_button=Like&hidden_image=http%3A%2F%2Flocalhost%2Fsplindr_2.0%2Fphotos%2FV2R80FX4Tgn6mdE%2Fskullwatercolor.jpg

Action = "get"? Do we SEE a problem here?!?

METHOD="GET".

ralston3

just one of those things that slips by you when you've been working on the same thing all day I guess. Cheers!

Actually, I just checked in my actual index.php page, and the method="GET", so I must've just mistakenly typed it in my post wrong. Still need to figure out why "GET" wont work.

Try turning that field on so you can see if you have a value in it before the action.

ralston3

Yea I did a

 vardump($image_info)

and the value turned out to be exactly what I want it to be. I just need to "GET" the value of that input field now.

deathshadow

Uhm, what does a echo '<pre>', print_r($_GET), '</pre>' show you?

what does the actual output markup look like from that form? Are there invalid characters in your $image_info?

I REALLY think we need to see a LOT more of your code to say what's going on.

that's fine. was just trying to show the relevant part but I can paste the whole index.php here:

error_reporting(E_ALL); ini_set('display_errors', 1); mysqli_report(MYSQLI_REPORT_ERROR | MYSQLI_REPORT_STRICT);

session_start();

	include('header.php');

                    var image_info = $(this).data('image'); 
                       $.ajax ({type:"POST", url:'like_button.php', data:{user:username, image:image_info}, success:function()

$likes_query = mysqli_query($conn, "SELECT * FROM `likes` WHERE `liked_img_loc` = '$liked_by'");

while($row = mysqli_fetch_assoc($likes_query))	{

	$liked_unliked = $row['liked_unliked'];

}

if($row['liked_unliked'] == 1)	{//user has already liked

	echo "<script type='text/javascript'>alert('Sorry, but you can not like an image twice!');</script>";

		} else {//user hasn't already liked the image

$sqli = "INSERT INTO `likes` (liked_img_loc, liked_by, liked_unliked, date) VALUES ('$liked_img_loc','$liked_by','$liked_unliked','$date')";

mysqli_query($conn, $sqli) or die ("No query");

header('location:index.php');

mysqli_close($conn);

		}
