I want to apply validation rules only for the input fields that are not empty (not required)
For example, If I submit a form and the input is empty, I got a validation error "Instagram Link must be valid url.", However, i want it without required, and if the input is not empty, i want to apply the rule "valid_url"
How can we fix it?
if (!$this->validate([
'instagram' => [
'rules' => 'valid_url',
'errors' => [
'valid_url' => 'Instagram Link must be valid url.',
],
],
])){
return redirect()->back()->withInput()->with('errors', $this->validator->getErrors());
}
I tried with a permit_link rule, but if I submit it (with the input value like 'mylink' (which is not a valid_url)), it will accept it, but it should not.
Please check the following images and the code: A form HTML Result after clicking on edit button
<?= form_open('/settings/edit/1', ['id' => 'setting-form']); ?>
<div >
<div >
<div >
<?= form_label('Instagram'); ?>
<?= form_input(['name' => 'instagram', 'class' => 'form-control', 'id' => 'instagram', 'placeholder' => 'Enter instagram link', 'value' => old('instagram', $setting->instagram)]); ?>
</div>
</div>
</div>
<button type="submit" >Edit</button>
<?= form_close(); ?>
public function edit($id)
{
if (!$this->validate([
'instagram' => [
'rules' => 'permit_empty|valid_url',
'errors' => [
'valid_url' => 'Instagram Link must be valid url.',
],
],
])) {
return redirect()->back()->withInput()->with('errors', $this->validator->getErrors());
}
die('submitted');
}
It should display "Instagram Link must be valid url" and not "submitted",

first
Use separate variable $rules
like this :
$rules = ['data' => 'require']
Then
check if $this->request->getVar("instagram");
is empty / is true or etc.. then set it on the $rules
finally
Do Something like this :
$rules = ['extra_data' => 'require'];
if(!empty($this->request->getVar("instagram"))
$rules["instagram"] = "valid_url";
if ($this->validate(rules){
//do something ...
}else {
//do something ...
}

I just noticed that the following examples: "mylink", "mylink.com", "https://www.mylink.com" will consider correct for the rule valid_url in Codeigniter (No errors), While: "https:://www.mylink.com", "mylink@" will apply the validation and the error is applied.
