php发布和重定向页面同时

Question

I am not php expert but i get stuck here. I have following three .php files

1. index.php <- drop down list, which select DB table.

2. query.php <- it craft json query.

3. chart.php <- it's highchart JQuery page. which use $.getJSON("query.php", function(json) { function to fetch data from query.php file.

index.php will get user input from drop-down list of select DB/Table and pass it to query.php and set SELECT * FROM $table variable.

But i want to do POST and at same time it will open chart.php page so i can direct redirect to chart page. How i send POST and Redirect same time so query.php get $table variable and instantly chart.php open chart.

EDIT:

If i put all my query.php code inside chart.php then how do i put those json values in $.getJSON() ?

$.getJSON("query.php", function(json) {
                options.xAxis.categories = json[0]['data'];
                options.series[0] = json[1];
                options.series[1] = json[2];
                options.series[2] = json[3];
                chart = new Highcharts.Chart(options);
            });

how $.getJSON() will get value from variable?

Answer 1

1) from index.php -> make POST request to chart.php with needed parameters

2) using $_POST on chart.php => receive data from index.php and show on template like :

for GET request to query.php

$.getJSON("query.php?<?='param1='.$_POST['param1']?>", function(json) {
                options.xAxis.categories = json[0]['data'];
                options.series[0] = json[1];
                options.series[1] = json[2];
                options.series[2] = json[3];
                chart = new Highcharts.Chart(options);
            });

or using usual $.ajax request send via POST request:

$.ajax({ 
         url: 'query.php',
         data: "<?='param1='.$_POST['param1']?>"
         dataType : "json",
         method:"POST",
         success: function(json){
                options.xAxis.categories = json[0]['data'];
                options.series[0] = json[1];
                options.series[1] = json[2];
                options.series[2] = json[3];
                chart = new Highcharts.Chart(options);
});

UPDATE

If your server don't have short_open_tag=On - use <?php echo 'param1='.$_POST['param1'] ?>

And check params before giving them on template
