I've done this stuff recently. I need to pass whole arrays betn. php and
Javascript (2-way), here is some code:
// PHP var. to JS
function arrFromStr (str2convert) { // make an array from string
arr = new Array();
var posOfQt1 = str2convert.indexOf('\"');
var posOfQt2 = str2convert.indexOf('\"', posOfQt1+1);
i = 0;
while(posOfQt1 != -1) {
arr[i] = str2convert.substring(posOfQt1+1, posOfQt2);
i++;
posOfQt1 = posOfQt2;
posOfQt1 = str2convert.indexOf('\"', posOfQt1+1);
posOfQt2 = str2convert.indexOf('\"', posOfQt1+1);
}
return arr;
}
Call this function like this:
layerDesStr = '<?=serialize($layerDes[0])?>';
layerDes[0] = arrFromStr(layerDesStr);
In case you have a variable don't serialize, just do
myJSvar = <?=$myPHPvar?>;
JS variables can be sent to PHP by including them in html forms, nothing
special about it.
