php - Submit more than one form in Javascript/ajax or jquery -


this trying have 3 forms in 1 page, need have because 1 form open in modal dialog, wish submit 3 forms when user click in single button, ajax implementation of sucess en error function in form submit 

<script src="https://code.jquery.com/jquery-2.1.1.min.js" type="text/javascript"></script> <script>  var firstformdata = $("#form1").serialize(); var secondformdata = $("#form2").serialize(); var thirdformdata = $("#form3").serialize();   $.post(     url: test.php                  firstformdata + secondformdata + thirdformdata );  </script>  <form id="form1"> <input type="text" name="one"></input> </form>  <form id="form2"> <input type="text" name="two"></input> </form>  <form id="form3"> <input type="text" name="three"></input> </form>  <button>submit here</button> <?php   echo $_post['one'];  echo $_post['two'];  echo $_post['three'];   ?>

you can following:

var combinedformdata = $("#form1,#form2,#form3").serialize();

this serialize 3 forms 1 query string. make sure input names don't overlap.

a complete implementation this:

<?php       // php code return html inserted in #result div       // demonstration purposes.       if (count($_post) > 0) {             echo "<p>you posted:</p><ul>";             foreach ($_post $key => $val) {                     echo "<li>$key: $val</li>";             }             echo "</ul>";             exit;       } ?> <html> <head>     <script src="https://code.jquery.com/jquery-3.2.1.min.js"></script> </head> <body>     <form id="form1">         <input type="text" name="one">     </form>      <form id="form2">         <input type="text" name="two">     </form>      <form id="form3">         <input type="text" name="three">     </form>      <button id="sendforms">submit forms</button>      <div id="result"></div>      <script type="text/javascript">         $(document).ready(function () {           $("#sendforms").click(function() {                    var combinedformdata = $("#form1,#form2,#form3").serialize();                  $.post(                         "test.php",                         combinedformdata                  ).done(function(data) {                         alert("successfully submitted!");                         $("#result").html(data);                  }).fail(function () {                           alert("error submitting forms!");                  })           });         });     </script>   </body> </html>

please note php code illustration , testing. should neither implement form handling this, nor put in same file form. it's bad style :-)
