[SOLVED] Passing Variables

[phatgreenbuds]

Consider the code below. How would I pass both the "$tblname" and "$display" through in the POST method?  Yes there is a bit of scripting before this that dynamically pulls the values for each and I need to somehow get them POST'd to the next step. Also is there anyway to do this without the need for a submit button? I have seen sites before that change the moment you change the selection and I cannot seem to figure out how to do that.

 

<form action="<?php $_PHP_SELF ?>" method="POST">
    <select name="table" size="1">		
            <option value="<?php echo $tblname ?>"><?php echo $display ?></option>
    </select>
    <input type="submit" name="submit" value="Submit">
</form>

$_POST['tblname'] = $tblname;

or use $_SESSION

 

that should do it, basically assign those variables to a superglobal

 

just a thought

[phatgreenbuds]

the $tblname passes thru fine but its the $display that I am having trouble with. There are 14 pair of those variables that can be chosen so assigning to a global doesn't work as each one has to change according to its partner.

huh?

 

little more info, maybe a bit more of your script

hidden field maybe? I don't really understand your question...

 

<input type="hidden" name="something" value="<?php echo $var; ?>" />

Are you supposed to have multiple options ($display), and only one table ($tblname)? Make $tblname the option name and the $display the option value.

[phatgreenbuds]

There is the value that is the actual table name and not exactly user-friendly something like blah_9_30_08. Then the correlating display to reference that table that is user-friendly like Sept 30th, 2008. Thus the two variables $tblname and $display. 

 

There are 14 of these combinations that can be selected and there is a new one added each day and an old one deleted everyday thru another automated script.

 

In order to start using this I want to pass both variables to the next page. I can pass the one as the value but how would I pass the other which is traditionally a display name in the drop down? Is that even possible using a drop down?

hmm...if there's a different $tblname $display combo for each choice then only thing I can really think of is to first create a multidim array and pass a whole array as a value. Example:

 

$data[0] = array ('tblname' => $tblname, 'display' => $display);
.
.
.
<option value = '{$data[0]}'>whatever</option>

ok thats interesting...never would have thought to do it that way. I will try it tonight.

<?php $_PHP_SELF ?>

should be

 

<?php echo $_SERVER['PHP_SELF']; ?>

I was able to solve this by changing from POST to GET variables. Thanks for the suggestions guys.
