Calling a JavaScript from PHP and processing return value

curare · December 23 '09, 02:04 PM (#1)

I'm doing some work with Google Maps and need to batch process some locations from a CSV import and return the lat/long values to input into a database. My geocode lookup works fine, but I need to be able to call my code from PHP and get the return values.

Currently, I have a form to input locations one at a time and just call my gecode onsubmit wich works perfectly. But how can I call a JavaScript routine from PHP directly?

I was thinking something along the lines of:

PHP Code:


			
<?php

...



$address_string = "123 Nowhere Ave., Somewhere, someplace, somezip, USA";



echo '<script type="text/javascript">find_location("$address_string"); return false;</script>';



...

?>

But I somehow have to get return values in my PHP, but one thing at a time. Any help is appreciated.

Hi,

I have done some coding for this in my previous project. It might help you, although not able to understand your problem fully.

Home.php

<form name="search" class="cmxform" id="homeForm" action="<?php echo base_url(); ?>search/result" method="POST">
</div>
<div class="searchWhat">
<input type="text" name="searchTxtBox" id="searchTxtBox">
</div>
<div class="searchWhere">
<input type="text" name="cityTxtBox" id="cityTxtBox" value="<?php echo $city_where;?>" onblur="showAddress(this);">
</div>
<input type="hidden" id="citylatlng" name="citylatlng">
</div>
<script type="text/javascript">
function showAddress(address) {
$("#citylatlng").val('');
var geocoder = null;
var geocoder = new GClientGeocoder();
geocoder.getLatLng(
address,
function(point) {
$("#citylatlng").val(point);
} );
}
</script>
<div class="searchBtn">
<input type="image" src="<?php echo base_url();?>images/c2c-btn.jpg"/>
</div>
</form>

Hope this coding will help you
