用PHP提交ajax表格

Question

I am having trouble getting the email to send which I am sure it is because of the php but here is the js ajax also..it shows my error messages for form fields that are not filled out correctly and then it shows my processing bar once submitted but I get my error message after submission..any help would be appreciated.

html

<form method="post" action="feedback.php" id="contactform">
            <fieldset class="first">


            <div id="response"></div>  


            <div id="name_input">

            <input id="name" name="name" placeholder="Name" class="required" type="text" maxlength="128" />

            </div>



            <div id="email_input">

            <input id="email" name="name" placeholder="Email"  class="required" type="text"  maxlength="128" />

            </div>



            <div id="budget_input">
            <label for="budget">Budget</label>
            <select id="mydropdown">
            <option value="none" selected=“”> -- choose one --</option>

Answer 1

can you try $.post instead of $.ajax

$.post(url, {argument_name: value, ...} , function(data){

// callback function..

}, 'json'}
