I am writing a inline-PHP snippet that is grabbing values out of a query.
Here is the code I use:
$(".menu-price-slider").each(function(index) {
console.log(timeToMinutes("<?php echo $query_results['d'.(++$d).'_o']?>"));
});
This code is giving me $query_results[1] every time, what I want is a counter that is increasing everytime this code gets executed.
$query_results[1], $query_results[2], $query_results[3], $query_results[4], etc.
Thanks in advance
OK. If you are expecting to get a different value for parameter of timeToMinutes with each iteration, then you are mistaken. I think you need to get a better understand for how PHP and javascript work. PHP is only working at the time of page render. One the page is rendered, javascript would work within the browser. If you didn't put all the values you need from PHP into the javascript source, you have no way to get to them after the page is rendered, short of using AJAX techniques you pull the data in after initial page render.
I might suggest a technique like this:
// pre-populate array of values from PHP
// here PHP $query_results must be numerically indexed array
// there should be equal number of elements in this array and
// .menu-price-slider DOM elements
var timeToMinutesParams = <?php echo json_encode($query_results); ?>;
// iterate through DOM elements,
// using index of element to get matching value from timeToMinutesParams
$(".menu-price-slider").each(function(index) {
console.log(timeToMinutes(timeToMinutesParams[index]));
});
You could make a file initialize it with 0 if it does not exist and if it exists read from it and at the end increase the number in the file.
$d = (isset($d) ? $d++ : 0);?
$dis initialized (presumeabe to 0) before, and in same scope as, your executions.
