[SOLVED] Fill fields with some value if I'm editing but also re-populating the form on submit

[eluser]ReyPM[/eluser]
Hi every, I'm building a CRUD for a table (not using any external tool) but I'm confused here while editing a record. As said here at docs Form Validation for re-populating the form I must use the set_value() function but what if I'm editing a record where value is populated from returned data by a previous query? How to handle the re-populating in this case? Any help or advice?

[eluser]CroNiX[/eluser]

Code:

set_value($field, $default);

$default will be used when the page first loads.
$field value will be used if the form was submitted.

It's (2nd paramter of set_value()) not explained in the Form Validation section of the User Guide, but it is in the Form Helper section.

Code:

set_value($field, $default);

$default will be used when the page first loads.
$field value will be used if the form was submitted.[/quote]

So if I'm right $default should be the value come from DB and $field should be the value for the re-populating? Also could you please write a small example in how logic should be from the controller? I'm lost here by the way thanks

[eluser]CroNiX[/eluser]
Yes.
controller

Code:

//get user data value for field1
$data['user_data'] = array('field1' => 'one'); //normally coming from db

//view

Code:

<input type="text" name="field1" value="<?php echo set_value('field1', $user_data['field1']; ?>" />

When the page/form first loads, it will have "one" for the value in the "field1" form field.
Once submitted, it will be whatever value was in the "field1" field.

Ok so there is not need for this code:

Code:

value="<?php echo!isset($article) ? set_value('number_pub', $article->NUMBER) : set_value('number_pub'); ?>"

[eluser]CroNiX[/eluser]
Nope, just 1 set_value() like I showed.

Ok, many thanks CroNiX

[eluser]ReyPM[/eluser]
Ahh one last question, what about SELECT, CHECKBOX and OPTION BUTTON? How to deal with those?

[eluser]CroNiX[/eluser]
Those have their own functions since they differ. See the bottom of the Form Helper section of the user guide.

Ok, I'll check also see this case (maybe I'm wrong)

Code:

$revista = array();
<?php echo set_value('id_revista', $revista->REVISTA); ?>

When $revista is empty I get this error:

A PHP Error was encountered
Severity: NoticeMessage: Trying to get property of non-objectFilename: articles/articles_form.php
Line Number: 37

Where line Number 37 is set_value ....
What I'm doing wrong here?
