send value through a form post

gabemcmillan

Hi, I need to display a value in my url through a form post. Here is what I have so far.

<form action=t4.php?affinity_select=<?php$_POST['affinity_select']?>" method="post">

Frederick

<form action=t4.php?affinity_select=<?php $_POST['affinity_select'];?>" method="post">

Place a space between the <?php and $
Also end the lin with ;

I modified it a bit, not sure if I am getting closer or not?

<form action="t4.php?affinity_select="<?php$_POST[affinity_select']?> method="post">

bodzan

<form action="t4.php?affinity_select=<?php echo $_POST['affinity_select']; ?>" method="post">

I that getting you anywhere?

Frederick

Ooops, missed the "echo" ey.

Okay, I think I am on the right track, when I go to the view source, it shows the correct thing:

but in the address bar, it shows:

http://www.affinityspot.com/t4.php?affinity_select=

?? How could this be?

bodzan

urlencode(), but I'm not sure if that will solve the problem...

That is, try:

<form action="t4.php?affinity_select=<?php echo urlencode($_POST['affinity_select']); ?>" method="post">

Post your whole form so we can see what elements are being used and what the form is used for.

<form action="t4.php?affinity_select=<?php echo $POST['affinity_select']; ?>" method="post">
<input type="hidden" name="redirect" value="<?php echo $POST['redirect'];?>">
<input type="hidden" name="affinity_id" value="<?php echo $REQUEST['affinity_id'];?>">
<input type="hidden" name="affinity_select" value="<?php echo $REQUEST['affinity_select'];?>">

City&nbsp<input type="text" name="city">
State&nbsp
<SELECT name="state_select">
<option value="" SELECTED><?php echo $row['state']; ?></option>
<?php
foreach( $states as $id => $state ) {
?>
<option value="<?php echo $state?>" ><?php echo $state?></option>
<?php
}
?>
</SELECT>
Zip&nbsp<input type="text" name="zip">

Within your&nbsp
<SELECT name="filter">
<option value="" SELECT></option>
<option value="city">City</option>
<option value="state">State</option>
<option value="zip">Zip code</option>
</SELECT>
<INPUT type="SUBMIT" name="SUBMIT" value="Search">

Ok, I found something interesting out. The first time I hit submit it doesn't show the value in the URL, the second and third time I hit submit it works fine? How could this be?

gabemcmillan

do i need to submit it twice when they hit the submit button?

Well, it appears you are looping back to the current page. You will not see any values untill you submit the form.
Use a default value if the one you want to display is not present.

<?php
$affinity_select = $_REQUEST["affinity_select"];
if (!empty($affinity_select)) { $affinity_select = $affinity_select;}
else ( $affinity_select = "default_value"; }
?>

<form action="t4.php?affinity_select=<?php echo $affinity_select; ?>" method="post">
<input type="hidden" name="affinity_select" value="<?php echo $affinity_select;?>">
