Putting inputs into inputs

LiamBailey

IS ther any way to put the value of a form into a hidden value in the action page.

Say I had a simple form
<form action="form2.php" method="post">
<input type="radio" name="variable" value="mine">
<input type="submit" value="submit">

then the PHP page is another form, and I want to enter $variable into the form

Would that work?

Yup... pretty much just like you have it:

<?php
$variable = (isset($_POST['variable']) ? htmlentities($_POST['variables']) : '');
?><!-- form stuff here... -->
<input type="hidden" name="viarablebox" value="<?php echo $variable; ?>">

Now what I want that value to be is a count that goes up one number each time the php is used is there anyway I could get it top up the value by one when or before it is inserted into the form. Or perhaps make the value=thevalue+1 everytime the form is submitted, feel free to send me somewhere to read up on functions etc, a link to a god place where I can find this kind of stuff without having to search function names, which I don't know, maybe the best help I could get.

if the form is going in to a db table simplely set one field (ie the id (key)) to be auto_increment otherwise you will have to store a count in a file or db and call it and increment it when ever the form page is called

If it's an increment you're wanting, just add a +1 onto the end of the variable in the echo() statement.

As for a link to read... well all you're doing is some simple math, so I guess you could peruse the different types of [man]operators[/man] in PHP.

But won't that bring the same number each time. I.e. creating the variable $count with value=1000

Then echo thevalue+1

1001

Everytime the script is ran.

I need to know how to make $count+1 the new $count value each time the script is run and the increment added.

dagon

store the count, either in a db or in a file

LiamBailey

How do I store it to a I have MySQL and know all my settings but am terrified to try it. Any help you could give me, e.g. even if only with a link to the right tutorial, will be greatly received.

Bradgafelman:

You told me this:

<?php
$variable = (isset($POST['variable']) ? htmlentities($POST['variables']) : '');
?>
<input type="hidden" name="viarablebox" value="<?php echo $variable; ?>">

In your second $_POST you have ['variables'] but I used variable for the purpose of my example, as you have in the first box, is this a typo or deliberate. It's not working for me

Also is the question mark in the middle meant to be a question mark.

benracer

the question mark is correct where it is as it closes the php scrip though it just looks odd.

should normally look like this...

<? $variable = (isset($_POST['variable']) ? htmlentities($_POST['variables']) : ''); ?>

good tutorial for this sort of thing here http://www.phpeasystep.com/phptu/7.html

It should be whatever POST variable you're using (and, of course, whichever variable was being checked by isset() in the conditional).

With the addition of 'php' after <?, yes.
