My boss purchased ACF PRO and i am using it to build out a multi-step form but the issue is acf doesn’t support multi-step forms out of the box. So what i have done is made my own custom validation using PHP AND JQUERY AJAX and this works fine for text fields but i can’t seem to get the data from the image field type.
Please view my code below and let me know if i am doing anything wrong. I just can’t seem to get the image data to store in the wordpress media library, image value is always empty.
Jquery:
$(“.nexttwo”).on(‘click’,function(){
resetErrors();
current_fs = $(this).parent();
next_fs = $(this).parent().next();
var comid = getUrlParameter(‘cid’);
var form = $(‘#ep-company-form’);
var companydata = new FormData(form[0]);
companydata.append(‘file’, document.getElementById(“acf-field_5bef0fac743f7”).files[0]);
companydata.append(“action”, “company_info”);
companydata.append(“cid”, comid);
$.ajax({
url: ajaxurl,
method: ‘post’,
data: companydata,
processData: false,
contentType: false,
dataType: ‘json’,
success: function(data){
//console.log(JSON.stringify(data));
for (var i = 0; i < data.length; i++) {
var status = data[i].code;
var field = data[i].field;
var message = data[i].msg;
//var comid = data[i].cid;
if (status == “200”){
//successful validation
if(animating) return false;
animating = true;
//activate next step on progressbar using the index of next_fs
$(“#progressbar li”).eq($(“fieldset”).index(next_fs)).addClass(“active”);
//show the next fieldset
next_fs.show();
//hide the current fieldset with style
current_fs.animate({opacity: 0}, {
step: function(now, mx) {
//as the opacity of current_fs reduces to 0 – stored in “now”
//1. scale current_fs down to 80%
scale = 1 – (1 – now) * 0.2;
//2. bring next_fs from the right(50%)
left = (now * 50)+”%”;
//3. increase opacity of next_fs to 1 as it moves in
opacity = 1 – now;
current_fs.css({‘transform’: ‘scale(‘+scale+’)’});
next_fs.css({‘left’: left, ‘opacity’: opacity});
},
duration: 800,
complete: function(){
current_fs.hide();
animating = false;
},
//this comes from the custom easing plugin
easing: ‘easeInOutBack’
});
} else {
var msg = ‘<label class=”acf-notice -error acf-error-message error” for=”‘+field+'”>’+message+'</label>’;
$(‘input[name=”‘ + field + ‘”], select[name=”‘ + field + ‘”]’).addClass(‘acf-error’).before(msg);
}
}
}
});
});`
