Default value dissapears

Hi,
I have a form asociated to a table.
In "Form Code" tab, in "Form HTML" I have added a hidden field:

<input id="myfield" name="myfield" value="tronco" type="hidden">

When I show this form in frontend I can see this field (viewing the source html of the page, of course). And its value is "tronco".

However, if I assign this form to a chronoconnectivity conexion as the "Record Edit Form", when editing a row, if I view the html code of the page:

<input id="myfield" name="myfield" value="" type="hidden">

i.e. the value is empty.
what is happening?

If you need access to my wev, please tell me.
Thanks a lot.

Hi jrariasf,

The Edit Record code reloads the form values from the corresponding database record. I'm guessing that there is no value for 'myfield' in the database - and possibly no column. If so the ChronoConnectivity id behaving logically.

I'm not quite sure why you'd need a fixed value in an editable record though?

If you do then you could probably re-write the value with JavaScript after the form has loaded.

Thanks GreyHead.
Really, I have not a fixed value. I have something like:

<input id="myuser" name="myuser" value="<?php echo $user->username; ?>" type="hidden">

Now I know that there must be a field in the database called "myfield" (or "myuser").

I will try in other way.
Thanks again.

Hi jrariasf ,

You never need to have the username in the form like this. You can always get it from the Joomla! User object after the form is submitted.

Good morning,
I imagine the "Yser objetc" you say is:

$user = &JFactory::getUser();

is this true?

By the way, in previous message you tell me "you could probably re-write the value with JavaScript after the form has loaded".
Could you tell me how can I do that?

I tell you what I have done:

1.- I have a table with 10 fields (one of this fields is "text_12").

2.- I have a form named "inscribirme_a_padel" to change the field "text_12".

3.- In the form, in "Form Code" tab, in "Form HTML" I have this:

<?php
// Get user-information from Joomla
$user = &JFactory::getUser();
?>

<div class="form_item">
  <div class="form_element cf_textbox">
    <label class="cf_label" style="width: 150px;">J1+</label>
    <input class="cf_inputbox" maxlength="150" size="30" title="" id="player_one" name="text_12" value="<?php echo $user->username; ?>" type="text" onclick="PutValue();" />
  
  </div>
  <div class="cfclear"> </div>
</div>

<div class="form_item">
  <div class="form_element cf_button">
    <input value="Submit" name="button_4" type="submit" />
  </div>
  <div class="cfclear"> </div>
</div>

And in "Form JavaScript" I have:

function PutValue()
{
   document.ChronoContact_inscribirme_a_padel.text_12.value='new_value';
}

4.- I have a "ChronoConnectivity conection" where the "Record Edit Form" is "inscribirme_a_padel".
When viewing the registers of the table, I show an "{edit_link}" in each row.

5.- If I click in the "edit_link" appears the form "inscribirme_a_padel" and when I click in the field then is called the "PutValue" javascript function.

Thats all right.

But...how can I re-write the value with JavaScript after the form has loaded without clicking the field?

* I have attached an screen capture with the form.

** A possible solution could be to add the onClick to the submit button. But I would like to know if exists a way of "re-write the value with JavaScript after the form has loaded".

Hi jrariasf ,

Apologies for my typo : Yser = User

This is a lot of work for something that isn't necessary but here's one way of doing it:

?php
// Get user-information from Joomla
$user = &JFactory::getUser();
$script = "
window.addEvent('domready', function() {
  $('player_one').value = '{$user->username}';
});
";
$doc =& JFactory::getDocument();
$doc->addScriptDeclaration($script);
?>

<div class="form_item">
  <div class="form_element cf_textbox">
    <label class="cf_label" style="width: 150px;">J1+</label>
    <input class="cf_inputbox" maxlength="150" size="30" title="" id="player_one" name="text_12" value="" type="text"  />
 
  </div>
  <div class="cfclear"> </div>
</div>

<div class="form_item">
  <div class="form_element cf_button">
    <input value="Submit" name="button_4" type="submit" />
  </div>
  <div class="cfclear"> </div>
</div>

Not tested but should work OK the only problem is that you need to make sure that this runs after the ChronoForms script that is re-loading the values.
