Input textfield to URL

DarkPrince2005 · September 21, 2009

I am trying to use the get function in php. I am setting the variables in the hyperlink url. But how would i set the content of a textfield into the url?

eg.

<div class="events">
<input type="hidden" name="elected_id2" value="<?php echo "$_POST[elected_id]"; ?>">
Cell:  <input type='text' size="15" name='cell'><br />
<center>[b]<a href="vote1.php?elected_id=<?php echo "$_GET[elected_id]"; ?>&cell=<?php echo "$_GET[cell]"; ?>"><img src="images/nextbut.gif" value="vote"></a>[/b]</center>
</div>

Hi DarkPrince2005,

The $_GET function, like you say, grabs the content of a URL and stores it into a defined variable. So, if my URL was:

http://www.somedomain.com/script.php?&name=bob&id=100

I could use the following PHP to store the two values into variables:

$name = $_GET['name'];
$id = $_GET['id'];

However, putting the contents of a textfield into a URL would not work for a number of reasons, if you want to pass the contents of a text field you must use the $_POST function.

I hope this helps.

I am basically doing a form for a mobi site, and most phones don't like the input type="image" or submit, so i'm trying to create a work around

Sorry but your question and latter response (along with your code) don't make much sense. Exactly what are you trying to do?

Bricktop · September 21, 2009

Hi DarkPrince2005,

What do you mean about phones not liking Submit? Do you mean that when a phone user clicks the submit button the script goes wrong? If so, it may be down to the way you are checking for a $_POST request.

A lot of people check for post with "isset" or if($_POST['blah'] == 'blah'] but these methods can cause problems, it's best to check for a $_POST request with:

if($_SERVER['REQUEST_METHOD'] == 'POST')

Not sure if this would help but it might be worth considering if you are having problems with your Submit code.

create pages and forms that don't make use of input types...

basically set all captured data into a hyperlink and post it that way...

Come on thorpe, you've givin e loads of good advice in the past.

Yeah, and if you'd post a decent description I might be able to help again. Explain the steps you are trying to make. Your code makes little sense as it is completely invalid.

DarkPrince2005 · September 21, 2009

the page layout is basically detrmined by if statements.

the firts screen gives you a bunch of images to vote on, after selecting an image it goes to the second page and asks you for your cellphone number. the third screen checks if it's a valid cellphone number and depending on that either checks the database or displays a form if it's not in the database

That doesn't describe any problem.

DarkPrince2005 · September 21, 2009

Most cellphones dont like the submit button or image...

Bricktop · September 21, 2009

What do you mean by that though DarkPrince2005?

Does the button appear? Does it not show? Does it not submit? Does it return an error message?

DarkPrince2005 · September 21, 2009

it doesn't submit and returns an error... "Request Invalid"

Bricktop · September 21, 2009

Even with the code I posted above?

if($_SERVER['REQUEST_METHOD'] == 'POST')

DarkPrince2005 · September 21, 2009

how would i incorporate that into my code?

Bricktop · September 21, 2009

Change every occurence of code similar to:

if (isset ($_POST['elected_id']) && $_POST['elected_id'] !="")

to

if($_SERVER['REQUEST_METHOD'] == 'POST')

DarkPrince2005 · September 21, 2009

if($_SERVER['REQUEST_METHOD'] == 'POST')?

How would I check what value is posted?

Bricktop · September 21, 2009

Just looked through your code and notice it's full of if(isset.... statements!

This is going to be tough, because of the way the code is structured it would need to be completely re-written to work with the if($_SERVER['REQUEST_METHOD'] == 'POST') method of checking for a POST request.

Also, none of your POSTed data is being validated or sanitised, these values are being directly entered into your MySQL query so it's best to perform some validation/sanitisation on these values.

Not sure of the best way to proceed with this, anyone else have any better ideas other than rewriting all the code?
