Question

我知道我在这里犯了错误，但我一整天都在寻找这个。我使用了yii2框架，我还是新手，我想访问partone/two页面，partone/two页面有两个提交按钮，一个用于添加行，第二个用于验证输入

在 PartoneController.php

中

<?
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; 
}

在 two.php

内

<?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>';
}?>

问题说明：

我想确定触发了哪个按钮，我已经指定了提交按钮的名称和值（ two.php 中的addRow按钮和nextPage按钮）。但是我使用Yii::$app->request->post('addRow') == 'true'无法获得 PartoneController.php 中的值，但失败了

我尝试的其他解决方案：我试图使用普通的html作为按钮，我不能在控制器yii中使用$_POST，编译器说

****这是我基于ScaiEdge反馈的更新代码：****

    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客户端：

    <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()?>

当我在客户端删除它时，它有效，任何人都可以解释原因吗？ $ item）{ echo addRelationForm（$ form，$ item，$ i）; } ？＆GT;

客户端变得像

    <?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函数：

  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>';

    }

Answer 1

您正在使用两个提交按钮，因此两个提交按钮之间会发生冲突。尝试将Yii :: $ app-＆gt; request-＆gt; post（'addRow'）更改为Yii :: $ app-＆gt; request-＆gt; post（'addmore'）下一页试试Yii :: $ app-＆gt; request-＆gt; post（'nextpage'）

Answer 2

只需使用ajax提交即可，然后做任何您想做的事情：

    $('.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 ...

Answer 3

可以从\ Yii :: $ app-> request-> post（'command'）

获取两个提交按钮的值。

向按钮提交按钮值但未能发布值
