submit button not working codeigniter - php

All i want is echoing 'a' when i click my button.
I have the following code in my view :
<?php echo form_submit('btnSearch', 'Search');?>
And this code in my controller :
if(isset($_POST['btnSearch']))
{
echo 'a';
}
This is my full code in the controller :
public function index() {
//table
$data_umat = $this->backend_m->get_umat()->result();
$this->table->set_heading(
'No',
'Nama',
'Kelas',
'Alamat',
'Sekolah',
'Nomor Telepon',
'Keterangan'
);
$table_template = array('table_open' => '<table border="1" id="custom_table">');
$this->table->set_template($table_template);
$no = 1;
foreach($data_umat as $list_temp)
{
$this->table->add_row(
$no++,
$list_temp->nama,
$list_temp->kelas,
$list_temp->alamat,
$list_temp->sekolah,
$list_temp->no_tlpn,
$list_temp->keterangan
);
}
$data = $this->backend_m->get_kelas()->result();
foreach($data as $row)
{
$data['list_kelas'][$row->kelas_id] = $row->kelas;
}
$data['table'] = $this->table->generate();
$this->load->view('backend/home_v', $data);
if(isset($_POST['btnSearch']))
{
echo 'a';
}
}
EDIT
And this is my view full code :
<body>
<div id="header"><h1>HEADER</h1></div>
<div id="side_menu">
<ul>
<li>Daftar Umat</li>
<li>Daftar Pengurus</li>
<li>Absensi</li>
</ul>
</div>
<div id="content">
<form>
<p>Search by Kelas :
<?php echo form_dropdown('kelas_id', $list_kelas, 'id="ddl_kelas1"');?> -
<?php echo form_dropdown('kelas_id', $list_kelas, 'id="ddl_kelas2"');?>
</p>
<?php echo form_submit('btnSearch', 'Search');?>
<?php echo $table?>
</form>
</div>
</body>
But the 'a' is not showing when i click the button. Where is my mistake? Thanks :D


You have not opened the form tag in HTML which you can see as bellow
<?php
echo form_open('Controller/Controller_Function');
echo form_dropdown('kelas_id', $list_kelas, 'id="ddl_kelas1"');
echo form_dropdown('kelas_id', $list_kelas, 'id="ddl_kelas2"');
echo form_submit('btnSearch', 'Search');
echo form_close();
?>
Now It should work. The first line is similar to
<form method="POST" action="Controller/Controller_Function">
Now It should be working.


You missed form tag. Please include that.
echo form_open('your_controller_name/index');
echo form_dropdown('kelas_id', $list_kelas, 'id="ddl_kelas1"');
echo form_dropdown('kelas_id', $list_kelas, 'id="ddl_kelas2"');
echo form_submit('btnSearch', 'Search');
echo form_close();
Now it will post to the controller function index()

Detail Page using CodeIgniter

I want to create a detail page, but when I click button examp_title, I can't move to Tryout/soal.
Thank You
Controller (Tryout.php)
public function deskripsi($tryout_id)
{
$data['tryout'] = $this->M_tryout->deskripsi_to($tryout_id)->row();
$data['exam_tpa'] = $this->M_tryout->get_exam_tpa($tryout_id)->result();
$data['exam_tps'] = $this->M_tryout->get_exam_tps($tryout_id)->result();
$this->load->view('tryout/deskripsi', $data);
}
public function soal($exam_code)
{
$data['soal'] = $this->M_tryout->get_soal_tryout($exam_code)->result;
$this->load->view('tryout/soal', $data);
}
View (deskripsi.php)
<?php foreach ($exam_tps as $key => $value) { ?>
<h5 class="fw-bold" class="sub_to">
<a href="<?php base_url('tryout/soal/') ?>
<?php echo $exam->exam_code?>">
<?php echo $value->exam_title;?>
</a>
</h5>
<p>
<?php echo $value->exam_duration;?> Menit,
<?php echo $value->exam_count_question;?> soal <br> Pembahasan
</p>
<?php } ?>

It looks like your <a> tag is not outputting the link you want due to a missing echo.
I have simplified the href below...
<h5 class="fw-bold" class="sub_to">
<a href="<?php echo base_url('tryout/soal/') . $exam->exam_code ?>">
<?php echo $value->exam_title; ?>
</a>
</h5>

This does not check whatever the string is empty. This check whatever there is a space. What you want is to check for "". If however it not supposed to continue follow Michiel suggestion.

How to validate tabular data in yii?

I have created a form which allows user to save tabular data. I have followed this tutorial . I have managed to add multiple instance for a Model and I am getting the data in the post and it is getting validate. The problem is with the error summary and the AJAX validation.
Below is my controller code, I have created an array for the second Model and passed it to the form.
$model = new UserAccountDetail;
$addresses = array();
array_push($addresses, new UserAddress);
array_push($addresses, new UserAddress);
$this->validateUserAccount($model,$addresses);
if(isset($_POST['UserAccountDetail']) && isset($_POST['UserAddress']))
{
$model->attributes = $_POST['UserAccountDetail'];
$model->validate();
$addresses = array();
for($i=0;$i<2;$i++)
{
if(isset($_POST['UserAddress'][$i]))
{
$address = new UserAddress;
$address->attributes = $_POST['UserAddress'][$i];
array_push($addresses, $address);
$address->validate();
}
}
}
$this->render('accountinformation',array('model'=>$model,'addresses'=>$addresses));
Below is my ajax validation function:
protected function validateUserAccount($model,$addresses)
{
if(isset($_POST['ajax']) && $_POST['ajax']==='user-account-detail-form')
{
echo CActiveForm::validate($model).CActiveForm::validateTabular($addresses);
Yii::app()->end();
}
}
When I run this code the Ajax validation does not work. The onclick validation does work but for the tabular data the messages are not shown in the error summary but the fields are highlighted in red.
I any thing else is required then please let me know.
Thanks for your time. Cheers!!!!!

Update : I have checked the response from the server and it is giving the correct response. Below is the screen shot:
Update :: I have managed to correct the on click validation issue by passing the array of models to the errorSummary() function like:
<?php
$error = array();
array_push($error, $model);
foreach ($addresses as $address)
{
array_push($error, $address);
}
echo $form->errorSummary($error); ?>
But the AJAX validation is still not working. Can any one help me with that.

http://www.yiiframework.com/doc/api/1.1/CActiveForm
The AJAX-based validation has a few limitations. First, it does not
work with file upload fields. Second, it should not be used to perform
validations that may cause server-side state changes. Third, it is not
designed to work with tabular data input for the moment.
So, you need to write custom error handler for tabular data
//view
$form = $this->beginWidget('CActiveForm', array(
'enableClientValidation' => true,
'clientOptions' => array(
'validateOnChange' => false,
'validateOnType' => false,
'validateOnSubmit' => true,
'beforeValidate' => 'js:formBeforeValidate',
'afterValidate' => 'js:formAfterValidate'
),
));
//some js
function formBeforeValidate (form) {
//clean errors
return true;
}
function formAfterValidate(form, data, hasError) {
if (hasError === true) {
//append errors to input
}
return !hasError;
}

There is no inbuilt mechanism in Yii to ajax validation for tabular data. I implemented custom validation using jquery for this purpose. Below is the code that I used to create a custom ajax validation for tabular data.
Controller: It assigns the value passed to the model attribute and returns any error for the attribute.
public function actionValidateData($value,$name)
{
$model = new BusinessPartner;
$model->setAttribute($name, $value);
$model->validate();
echo CHtml::error($model,$name);
Yii::app()->end();
}
Jquery function to make ajax call and show the messages. I have added class 'businessPartner' to all the fields of the model.
$(document).on('blur','.businessPartner',function(e){
e.preventDefault();
var id= $(this).attr('id');
var name= $(this).attr('rel');
$.ajax({
url:"<?php echo Yii::app()->createUrl('user/validatedata'); ?>",
type: "GET",
data: 'value='+$.trim($(this).val())+'&name='+ name,
success :function(data){
if($.trim(data))
{
if(!$('#'+id).hasClass('error'))
{
$('#'+id).addClass('error');
$('#'+id).prev().addClass('error');
$('#'+id).after(data);
}
}
else
{
if(!$('#'+id).parent().hasClass('success'))
{
$('#'+id).removeClass('error');
$('#'+id).prev().removeClass('error')
$('#'+id).next().remove()
$('#'+id).parent().addClass('success');
}
}
},
error:function(){
},
});
});

Tabular Input Yii

I have to input several strings into table in db. Its tabular input yii. Cannot understand, how to do it this way, if i have such controller:
public function actionCreate()
{
$model1=new Section;
$model2=new SectionI18n;
if(isset($_POST['SectionI18n'])){
foreach ($model2 as $i => $m1) {
foreach($_POST['SectionI18n'] as $i => $m1)
{
$m1=new SectionI18n;
$m1->attributes=$_POST['SectionI18n'][$i];
$my[]=$m1->attributes;
}
}
and some layout:
<?php foreach ($model2 as $i=>$m1):?>
<?php ?>
<div class="row">
<?php echo $form->labelEx($model2,'Название'); ?>
<?php echo $form->textField($model2,'[$i]title',array('size'=>60,'maxlength'=>100)); ?>
<?php echo $form->error($model2,'title'); ?>
</div>
<div class="row">
<?php echo $form->labelEx($model2,'Описание'); ?>
<?php echo $form->textArea($model2,'[$i]description',array('size'=>60,'maxlength'=>200)); ?>
<?php echo $form->error($model2,'description'); ?>
</div>
<div class="row">
<?php echo $form->labelEx($model2,'Язык'); ?>
<?php echo $form->dropDownList($model2,'[$i]lang',array('ru'=>'ru','en'=>'en','ua'=>'ua')); ?>
<?php echo $form->error($model2,'lang'); ?>
</div>
<?php ?>
<?php endforeach;?>
Help please

It would be something similar to this:
foreach ( $_POST[Model Name] as $i => $y ){
$var name[$i] = new Model Name;
$var name[$i]->title = $_POST[Model Name][$i][title]
...
}
var_dump the post ($_POST), object makes it easier to see.
