Formatting form error messages - php

Question

Form code :
$this->add(array(
'name' => 'username',
'type' => 'Text',
'options' => array(
'label' => 'Username',
),
));
model :
$inputFilter->add(array(
'name' => 'username',
'required' => true,
'filters' => array(
array('name' => 'StripTags'),
array('name' => 'StringTrim'),
),
'validators' => array(
array(
'name' => 'NotEmpty',
'options' => array(
'messages' => array(
\Zend\Validator\NotEmpty::IS_EMPTY => 'Username required',
),
),
),
array(
'name' => 'StringLength',
'options' => array(
'encoding' => 'UTF-8',
'min' => 5,
'max' => 69,
),
),
),
));
View :
$form->setAttribute('action', $this->url('signup', array('action' => 'signup')));
$form->prepare();
echo $this->form()->openTag($form);
echo $this->formRow($form->get('username'));
then I get output like following :
It seems every individual part of ‘Zend\Validator’ works alone and throws error message individually. I want to display the required message only if the field is empty, not the stringlength. How can I do that ?
-Thanks.
Update :
I did the following in the 'view' page :
echo $this->formRow($form->get('username'));
foreach($form->getMessages() as $key=>$value){
if($key=="username"){
if(isset($value['isEmpty'])){
echo $value['isEmpty'];
}else if(isset($value['stringLengthTooShort'])){
echo $value['stringLengthTooShort'];
}else if(isset($value['stringLengthTooLong'])){
echo $value['stringLengthTooLong'];
}
}
}
then got the output :
now there are two error messages in unordered list still being there. how can I remove those messages and keep my formatted message only ?
Solved :
I had to do the following :
View :
$errmsg = $form->getMessages();
echo $this->formLabel($form->get('username'));
echo $this->formInput($form->get('username'));
if ($errmsg) {
if (isset($errmsg['username'])) {
foreach ($errmsg['username'] as $key => $value) {
?>
<span class="formerror">
<?php
if ($key == "isEmpty") {
echo $value;
break;
} else if ($key == "stringLengthTooShort") {
echo $value;
break;
} else if ($key == "stringLengthTooLong") {
echo $value;
break;
}
?>
</span>
To format the error messages I can’t use ‘formelementerrors’ because it returns string (ref: http://framework.zend.com/manual/2.0/en/modules/zend.form.view.helpers.html#formelementerrors), not array. so its easy to identify individual errors by keys if I use ‘getMessages()’.

Answer 1

In your controller you can use this method for retrieve the errors messages :
$form->getMessages();
Is an array and you can use a foreach to retrieve the key 'isEmpty' and display this.
