gform_post_render and populate_post with ajax request WordPress

ProjectAgile comments:

Put code in functions.php--right? Would need to specify form ID #23.

Rempty comments:

Yes i forgot

add_filter('gform_pre_render_23', 'populate_dropdown');


ProjectAgile comments:

FYI: The ajax request sends the customers' prescription values to the package_check.php to process the values, then ajax returns package options.

Rempty comments:

Yes, just want to know if, the post variables are accesible here function populate_dropdown($form), because each time you press next, the post variables are propagating via ajax.
With this $_POST variables you can get the json via file_get_contents with all your data. (all via php no js)

It works and you're on the right track but I need to pass the Sphere and Cylinder and other field option values to the ajax request so the package_check.php can determine the appropriate package options and prices. There are over 100 combinations so conditional logic won't work nor will the pre render filter. I will add more $

The question was how to include field #IDs in Ajax request. For example, replace '+rxtype+' with actual form field ID to send values. I think '+#input_23_8'

23 is Form ID and #8 is field for OS Cylinder

Here's ajax again and I attached the package_check.php

$.ajax({

url: '/package_check.php',

type: 'POST',

dataType: 'text',

data: urlData,

success: function(data) {

var packages = $.parseJSON(data);

$.each( packages, function( key, value ) {

var price = parseFloat(value['price']).toFixed(2)

packages_content += "<option value='"+value['package_name']+"#"+price+"#"+value['ar']+"'>"+value['package_name']+" $"+price+"</option>";

e



if })

packages_content += "</select>";

$('#container_lens_package').html(packages_content);

}

})

If you want to continue via js, get the form ID "gform_21"

var formid=jQuery('#content .post-content form').attr('id');


Via PHP

//Formid
$_POST['gform_submit'];

//Field ID 59 //OD Sphere)
$_POST['input_59'];

//Field ID 20 //OD Cylinder)
$_POST['input_20'];
...
//Field ID 29 //Prism)
$_POST['input_29.1'];

//Field ID 212 //Lens type
$_POST['input_212'];



//To get the json sending post data
//Example
$postdata = http_build_query(
array(
'var1' => 'some content',
'var2' => 'doh'
)
);

$opts = array('http' =>
array(
'method' => 'POST',
'header' => 'Content-type: application/x-www-form-urlencoded',
'content' => $postdata
)
);

$context = stream_context_create($opts);

$json = file_get_contents('http://example.com/submit.php', false, $context);
$obj = json_decode($json);
//json will be a object

Gravity form's technical support told me I probably need to use the gform_post_render with the populate_dropdown but your method appears more efficient. However, I don't know if post variables are accessible but I would think so.

Rempty comments:

You can use gform_post_render and replace the ul content, adapt your code and get a li

<li class="gchoice_21_162_0"><input name="input_162" value="1.50 Standard|110" id="choice_21_162_0" tabindex="185" type="radio"><label price=" -$65.00" for="choice_21_162_0" id="label_21_162_0">1.50 Standard<span class="ginput_price"> -$65.00</span></label></li>

Now i understand your question, you dont know how get values via Jquery


var odsphere=jQuery("#input_21_59").val();
