Passing input value from one page to another

I’m fairly new at this. I’m trying to build a store locator and trying to figure out how to pass an input value from one page to another page. User would input their zipcode or address in a form on one page and the map and locations would be called on another page using the input.

I’m using ehound store locator platform (sample - here ->

The map/locator script is this

and the form itself would be on another page. Trying to pull the address input over. This obviously doesn’t work

    <input type="submit" name="search" value="Address Search">


I’ve looked around on passing inputs via php and such, but this script seems to call on javascript as well and I’m having trouble implementing anything that works. Any help would be greatly appreciated.

That javascript (it is an entire webpage) performs all the proximity search operations ‘in place’. Take note of the “Initialize” method near the top. It instantiates a google.Maps object (which inherently writes to the ‘map_canvas’ dive element.

    map = new google.maps.Map(document.getElementById("map_canvas"), myOptions);

If you use that page as your “goto” page, you can use PHP to pass variables into those Javascript functions.
This requires setting the “address” variable here

    var address = document.getElementById("address").value;

And calling ‘searchAroundMe();’ after a call to ‘Initialize();’

Well, if you’re using php, you could grab it from the $_POST global array. If you only want to use javascript, you can use get instead of post and grab in the value from the url on the next page via window.location.href…

So could I do this? Pass through PHP. Then change this

 var address = document.getElementById("address").value;

in the searchAroundMe() function to

 var = <?=$_POST['address'];?>


Then are you saying do

<body onload="initialize(); searchAroundMe()">


It’s not working. I suck. I also tried passing the PHP variable into the form like so

     <form action="" onsubmit="searchAroundMe(); return false;" name="locatorForm">
    <input id="address" type="textbox" value="<?=$_POST['address'];?>">
    <input type="submit" name="search" value="Address Search">

<SCRIPT LANGUAGE="javascript">

and doing a javascript auto submit, but it just keeps looping. Help!

That is the idea I was proposing. I am not sure why it did not work for you.
Have you taken a look at the “View Source” on the PHP page; to verify the ‘address’ was written into the javascript “var” as expected?

Standard troubleshooting techniques mandate you take it one step at a time.
Verify you are passing the POST parameters correctly from your ‘form’ page to the ‘javascript’ (output) page.

Yes, Thank YOU! I got it working. I’m learning everyday. :slight_smile:
