How Do I loop through this POST array? - php

Question

I have data that is being passed through an POST method. However when I try to get some data out of it and set it to a session variable, there is no data in it yet when I print_R($_POST) I see there is Data in it.
This is What I'm getting when I print_r() the POST data.
Array (
[_csrf] => nXRvIHfHWeao64YBdwcdFJa3fz-KShIyAuHDNtKQqhCkDRdwErUqkOrSyHQQamtR5cBHWc57QUNq16hflaftKQ==
[LoginForm] => Array (
[compayname] =>Termite Soup
[username] => Jim.Bot
[password] => 123456
[url] =>
)
[login-button] =>
)
This is what I've tried.
This is the form where form is being filled.
<?php $form = ActiveForm::begin([
'id' => 'login-form',
'layout' => 'horizontal',
'fieldConfig' => [
'template' => "{label}\n<div class=\"col-lg-10\">{input}
</div>\n<div class=\"col-lg-8\">{error}</div>",
'labelOptions' => ['class' => 'col-lg-3 control-label'],
],
]);
?>
<?php echo $form->field($model,
'compayname')>dropDownList(['GF_TB_TNT' => 'GF-TNT',
'Chicken Soup' =>'Dog Soup',
'Termite Soup' =>'Termite Soup',
],
['prompt'=>'Select Company']); ?>
<?= $form->field($model, 'username')->textInput(['autofocus' => true]) ?>
<?= $form->field($model, 'password')->passwordInput() ?>
<?= $form->field($model, 'url')->hiddenInput()->label(''); ?>
<div class="row">
<div class="btn-group">
<!-- <div class="col-md-2">
</div> -->
<div class="col-md-6">
<?= Html::submitButton('Login', ['class' => 'btn btn-primary pull-left', 'name' => 'login-button','style'=>'font-size: 15px;']) ?>
</div>
Getting the data and setting it to a Session Variable
if (Yii::$app->request->post()) {
$companyname = Yii::$app->request->post('compayname');
}
I want to set the companyname in the POST to a session Variable

Answer 1

What you can do is
foreach (Yii::$app->request->post('LoginForm') as $field) {
// some logic
}
Also I see a mistake in compayname. A "n" is missing in the word. But you can access it's value by Yii::$app->request->post('LoginForm')['compayname'];

Answer 2

You can shortly get this.
$arr = [];
foreach ($_POST as $param) {
if (is_array($param)) {
foreach ($param as $name) {
if ($name == 'LoginForm') {
array_push($arr, $name);
}
}
} else {
}
}
And you can figure out how the data is structured using var_dump
var_dump($arr);
