Dear all
I'm a newbie in PHP, jQuery and bad in English.
I want to ask about jQuery modal dialog rules, from database. This is my database:
This is my code: Javascript rules and jQuery Validate without the load of the database:
rules: {
user: {
required: true,
number: true,
range: [1, 8]
}
},
messages: {
user: {
required: "* sorry field user empty.",
number: "* Field user must number.",
range: "* Field user must between 1 to 8"
}
}
I used PHP and this is my form field, from the user only.
<?php $user = array(
'name' => 'user',
'id' => 'user',
'class' => 'user',
'value' => '',
'style' => 'border: groove 2px;',
'size' => '3',
'maxlength' => '3'
); ?>
<td> <?php echo form_label('User');?> </td>
<td> : </td>
<td> <?php echo form_input($user); ?></td>
The question is how to input rules with load a database.
For example:
If I login with userdata and load the database the $items value is 8.
echo $this->session->userdata('items')
Are the range rules automatically between 1 to 8? Like the following image:
And, if the login userdata to load database $items value is 6, are the range rules automatically between 1 to 6? The same question if $items is 4.
I need your help.
Thank you so much for your attention.
Best regards,
Puja
I am not sure what form_input() does but you can try adding variable to input and extract it when attaching validation rules
$user = array(
'name' => 'user',
'id' => 'user',
'class' => 'user',
'value' => '',
'style' => 'border: groove 2px;',
'size' => '3',
'maxlength' => '3',
'data-range' => $this->session->userdata('items')
);
And in javascript code
rules: {
user: {
required: true,
number: true,
range: [1, parseInt($('#user').data('range'))]
}...
If data will not be added to the generated input field you can try add this to class, for example
'class' => 'user range_'.$this->session->userdata('items'),
and in js change
parseInt($('#user').attr('class'))
to
parseInt($('#user').attr('class').substring($('#user').attr('class').indexOf('range_')+6)); //add 6 as this is the length of range_
