hello, i’m trying to populate a view file to edit user’s profile.

<select name="role">
        <option value="">select a role</option>
        <? foreach ($roles as $role): ?>     
                
                <? ($role->id == $user->role) ? $default=TRUE : $default=FALSE; ?>
        <option value="<?= $role->id ?>" <?= set_select('role', $role->id, $default) ?> > <?= $role->name?> </option> 
        <? endforeach; ?>
</select> 

the problem is that no default value is selected, what’s the solution.

This isn’t a ternary operator.

<? ($role->id == $user->role) ? $default=TRUE : $default=FALSE; ?>

What you can do is if you are using the same number of rolID in the select (dropdown) index control just do something like this

$arrayRoles = array();                
foreach ($roles as $key => $value) {
    //$arrayRoles[0] = "Admin"
    //$arrayRoles[1] = "AnyOther"
    $arrayRoles[$key] = $value["rol"];  
}

//so $selected would be the index of the array $arrayRoles[]
$selected = 0;

<?=form_dropdown("roles", $arrayRoles, $selected);?> 

So, you will have something similar

<option selected="selected" value="0">Admin</option>
<option value="1">AnyOther</option> 

Cheers!

tnx 4 ur reply, if i understand what you mean, i could also have used something similar to

<select name="role">
        <option value="">select a role</option>
        <? foreach ($roles as $role): ?>     
                <?  ($role->id == $user->role) ? $selected='selected' : $selected=''  ?>
                
        <option value="<?= $role->id ?>" <?= $selected ?> > <?= $role->name?> </option> 
        <? endforeach; ?>
    </select> 

which would select the users role on initial load of the page, but how do i then handle repopulating the new selected value in case of an error after

$this->fom_validation->run() 

Hence i’m trying to achieve two things, auto-select the users role in the DB on load of the page, and re-populate d selected value after the edit form is submitted in-case there’s an error.

The one for text input boxes work as desired, but i’m having problem with that of the select drop-down

<label for="email">Email address:</label> <input type="text" name="email" value="<?=  set_value('email', $user->email)?>" />

I am not sure, I haven’t tested but why don’t you just use the form_dropdown() function of the form helper?
The third param of that function receive the value you wish to be selected.

Cheers!

This isn’t a ternary operator.

<? ($role->id == $user->role) ? $default=TRUE : $default=FALSE; ?> 

As he said, this is ugly. You can assign the true/false result of a conditional to a variable instead - much cleaner.

$default = ($role->id == $user->role); 

You could even use the conditional directly in the set_select() function. Not as easily readable, but still valid.

Also, I agree to just using form_dropdown(). Then you can specify $user->role as the third parameter and it will be the default value.
