Export Javascript When The Script Is Using Php Variables
Solution 1:
Add all these php-generated variables as parameters of your function:
functionvalidateCostCenter(el, local_plan_ID, cc_plants_array, std_cs_array)
BTW you could use json_encode to export your $employers array to javascript.
Solution 2:
I will illustrate possible approaches on a very simple example.
Approach 1: Computation in PHP
The page.php contains the computation and the generated Javascript file (as you have it now):
<body><?phpfunctionsum_php($a) {
$sum = 0;
for ($i = 0; $i < count($a); ++$i) $sum += $a[$i];
return$sum;
}
$a = array(1, 2, 3);
$sum = sum_php($a);
?><scripttype="text/javascript">// JS generated by PHP:alert("sum_php=" + <?phpecho$sum?>);
</script></body>Approach 2: Computation in Javascript
The computation is moved out of PHP into a separate Javascript file page.js. PHP supplies the variables to the JS functions by JSON-encoding:
(1) page.php:
<head><scripttype="text/javascript"src="page.js"></script></head><body><?php$a = array(1, 2, 3);
?><scripttype="text/javascript">
sum_js(<?phpecho json_encode($a) ?>); // supply $a to JS function</script></body>(2) page.js:
functionsum_js(a) {
var s = 0;
for (var i = 0; i < a.length; ++i) s += a[i];
alert("sum_js=" + s);
return s;
}
Solution 3:
Assumiong that these values are non-cacheable....
If it were me, I'd have a PHP create a global object/array to hold the values, and generate non-cacheable javascript file, then move the rest of the code into a static, cacheable file, e.g.
user_vars.php:
<?php
session_start();
....get values for variables....
print"user_vars={";
print" ' plant': " . json_encode($plant) . "\n";
print" ', cc_plants_array: [" . $cc_plants . "]\n";
....etc
generic.js:
functionvalidateCostCenter(el){
var objCB = el;
var emp_code = objCB.name.substring(23,29);
var local_plant_ID = user_var.Plant.LocationID;
var cc_plants_array = user_var.cc_plants_array;
.....
However unpicking what the generated values for each parameter will be can be a bit tricky - the simplest approach might be to write a temporary file as PHP generates the base HTML rather than try to create the data structures twice.
