问题
I know i have made mistakes here but i have been searching for this for the whole day.
I used yii2 framework and i am still new here,
I want to access partone/two page, the partone/two page has two submit buttons, one is for adding row, the second one is for validating the input
inside PartoneController.php
<?
public function actionTwo() {
if(\Yii::$app->user->isGuest) {
$this->goHome();
}
$models = [];
$val = "" ;
//Create array of items
Yii::trace("Lets start: ");
if(Yii::$app->request->post('addRow') == 'true'){
Yii::trace("hello");
Model::loadMultiple($models, Yii::$app->request->post('items'));
$model = new RelationForm();
array_push($models, $model);
return $this->render('two', ['items' => $models]);
}
if (Model::loadMultiple($models, Yii::$app->request->post('items')) && Model::validateMultiple($models))
{
Yii::trace("hello again");
$count = 0;
for($i = 0 ; $i < $models.length(); $i++){
if(strpos($relationShownCurrently, '' + $i) !== FALSE){
if(!$items[$i]->store()){
return $this->render('two', [ 'items' => $models ]);
};
}
}
Yii::$app->session->setFlash('success', "Processed {$count} records successfully.");
return $this->redirect(['index']); // redirect to your next desired page
} else {
for($i = 0; $i < 5 ; $i++) {
$models[$i] = new RelationForm();
}
return $this->render('two', ['items' => $models]);
}
return null;
}
inside two.php
<?php
use yii\app\clientScript;
use yii\bootstrap\ActiveForm;
use yii\helpers\Html;
use frontend\models\relation;
$this->registerJsFile('http://code.jquery.com/jquery-2.1.4.min.js');
function addRelationForm($form, $item, $i){
return '<div class="col-md-12" id=\'r_'.($i).'\'>
<div class="form-group col-md-12">
<label> Friend ' . ($i + 1) . '</label>'.
$form->field($item, "user_friend_id[$i]") .
'<label> Closeness to you </label>
<div class="form-inline"> ' .
$form->field($item, "[$i]closeness")->radio(array("label" => "1", "value" => 1)) .
$form->field($item, "[$i]closeness")->radio(array("label" => "2", "value" => 2)) .
$form->field($item, "[$i]closeness")->radio(array("label" => "3", "value" => 3)) .
$form->field($item, "[$i]closeness")->radio(array("label" => "4", "value" => 4)).
$form->field($item, "[$i]closeness")->radio(array("label" => "5", "value" => 5)) .
'</div>'
.'<div class="form-inline" >
I know this person as a friend for approximately (in year) '.
$form->field($item, "[$i]known_for")->textInput(["type" => "number", "placeholder" => '(in year)'])->label(false).
'</div>'.
'</div></div>';
}?>

Problem Explanation:
I want to determine which button is fired, i have specified the name and the value of the submitbutton (addRow button and nextPage button in two.php). But i could not get the value in PartoneController.php by using Yii::$app->request->post('addRow') == 'true', but failed
Other Solutions I have tried:
I have tried to use normal html for the button, and i cannot use $_POST in controller yii, the compler says
**** This is my updated code based on ScaiEdge Feedback:****
public function actionTwo(){
if(\Yii::$app->user->isGuest){
$this->goHome();
}
$models = [];
$val = "" ;
$submit = Yii::$app->request->post('command');
for($i = 0; $i < 5 ; $i++){
$models[$i] = new RelationForm();
}
//Create array of items
Yii::trace("command: " .$submit);
if($submit == 'addmore'){
Yii::trace( "hello");
Model::loadMultiple($models, Yii::$app->request->post('items'));
$model = new RelationForm();
array_push($models, $model);
return $this->render('two', ['items' => $models]);
}
if (Model::loadMultiple($models, Yii::$app->request->post()) )
{
Yii::trace("hello again");
$count = 0;
for($i = 0 ; $i < count($models); $i++){
if(!$models[$i]->validate()){
if($models[$i]->hasErrors()){
Yii::trace( Html::errorSummary($models[$i] ));
}
return $this->render('two', ['items' => $models]);
}
}
for($i = 0 ; $i < count($models); $i++){
if(!$models[$i]->store()){
return $this->render('two', ['items' => $models]);
}
}
Yii::$app->session->setFlash('success', "Processed {$count} records successfully.");
return $this->redirect('three', ['items' => $models]);// redirect to your next desired page
}
else {
return $this->render('two', ['items' => $models, 'submit' => $submit ]);
}
return null;
}
Html Client Side:
<h1>Friendship Survey</h1>
<p> Introverted the space below, list up to ten of your closest friends that are currently in Econs/ Math and Econs; a minimum of 5 is compulsory. *Please select their full names from the dropdown list provided. Also, please select on the scale how close you are to each friend. 1Note the incentives for this section </p>
<?php $form =ActiveForm::begin() ?>
<?php foreach ($items as $i => $item) {
echo addRelationForm($form ,$item, $i);
}
?>
<hr>
<div class="row">
<div style="float:left" >
<?= Html::submitButton('Add Row', [ 'name' => 'command', 'value' => 'addmore', 'class' => 'btn btn-info']) ?>
</div>
<div style="float:right" >
<?= Html::submitButton('Next Page', ['class' => 'btn btn-primary', 'name' => 'command', 'value' => 'nextpage']) ?>
</div>
</div>
<?php ActiveForm::end()?>
When i removed this in the client side, it works, can anyone explain why? $item) { echo addRelationForm($form ,$item, $i); } ?>
the client side become like
<?php $form =ActiveForm::begin() ?>
<hr>
<div class="row">
<div style="float:left" >
<?= Html::submitButton('Add Row', [ 'name' => 'chosen', 'value' => 'addmore', 'class' => 'btn btn-info']) ?>
</div>
<div style="float:right" >
<?= Html::submitButton('Next Page', ['class' => 'btn btn-primary', 'name' => 'chosen', 'value' => 'nextpage']) ?>
</div>
</div>
<?php ActiveForm::end()?>
addRelationForm function:
function addRelationForm($form, $item, $i){
return '<div class="col-md-12" id=\'r_'.($i).'\'>
<div class="form-group col-md-12">
<label> Friend ' . ($i + 1) . '</label>'.
$form->field($item, "[$i]user_friend_id") .
'<label> Closeness to you </label>
<div class="form-inline"> ' .
$form->field($item, "[$i]closeness")->widget(RangeInput::classname(), [
'options' => ['placeholder' => 'Rate (1 - 5)...'],
'html5Options' => [
'min' => 1, 'max' => 5,
'width' => '75%',
'addon' => ['append' => ['content' => '<i class="glyphicon glyphicon-star"></i>']]
]])->label(false).
'</div> '.
'<div class="form-inline" >
I know this person as a friend for approximately (in year) '.
$form->field($item, "[$i]known_for")->textInput(["type" => "number", "placeholder" => '(in year)'])->label(false).
'</div></div></div>';
}
回答1:
You are using two submit buttons,so the conflict occur in between two submit buttons. Try changing Yii::$app->request->post('addRow') to Yii::$app->request->post('addmore') for next page try Yii::$app->request->post('nextpage')
回答2:
just do your submission with ajax and do whatever you want :
$('.yourForm').on('submit', function (event) {
event.preventDefault();
var formdata = new FormData(this);
var whatEverInAddition = $('SelectYourDesiredElements').val();
formdata.append("whatEverInAddition", whatEverInAddition );
$.ajax({
url: ...
and so on ...
回答3:
The value of your two submit buttons can be obtained from \Yii::$app->request->post('command')
