[JavaScript] Send Data back to opener[RESOLVED]

Hey I am trying to send some data from a window i opened into a textbox that is on the main window.

the code in the new window

Code:

---

  <script language="javascript">
  function refresh_media(selected_media)
  {
          opener.document.forms['article'].article['test'].value += "[media=" + selected_media + "]";
  } </script>
 <input type="button" class="button" value="Insert Selected Media" onClick="refresh_media(this.form.media_list.options[this.form.media_list.selectedIndex].value);return false;" />

---

code in the parent window

Code:

---

  <form method="post" name="article">
  <input type="text"  name="article[test]" />
  </form>

---

The error i get when debugging is

Quote:

---

Error: opener.document.forms.article.article has no properties

---

If i change the name of the textbox from "article[test]" to just "test" then it works, but i want the form items like an array so that i can easly process the data via PHP.

Thanks

If you have more than one intput element with the same name in your form then the elements will be put into a javascript array.

HTML Code:

---

                <form name="test">
                        <input type="text" name="test[]" />
                        <input type="checkbox" name="test[]" />
                </form>
                <script type="text/javascript">
                        <!--
                        // number of elements in the array
                        alert(document.test['test[]'].length);

                        // an array items value
                        alert(document.test['test[]'][0].value);
                        //-->
                </script>

Make sure you use index notation when accessing form elements with square brackets in their names as these are javascript meta characters.

** no **P.s: The name article[test] won't get passed to PHP as an array. You need to name it article[] with empty square brackes for PHP to create an array.

VisualAd you can pass an array to PHP with an form item name of article[name].

When i get it from PHP its like $_GET['article']['test'] and it works fine

I havent tried out the code yet because im not at home. ill try it later

thanks

Nice - I never actually realised that. The same still applies in the other post though, except for that line ;)
