Caricare pagine via AJAX

International Italian
1

Salve a tutti e da un po’ che non posto su questo forum, anche perchè devo dire che una volta presa la mano con

yii non sto avendo particolari problemi :D

Passo subito alla domanda, avrei necessità di creare un ajax call che mi vada a riprendere un form relativo ad un model. Mi spiego meglio, ho creato una pagina in site/pages chiamata clienti.php

In questa pagina ho solo (momentaneamente) due checkbox. Cliccando su una delle checkbox vorrei che alla pagina

(clienti.php) venisse "appeso" il form realtivo alla scelta della checkbox che può essere azienda o privato.

Ho provato in questo modo:

clienti.php




<h1>Nuovo Cliente</h1>

Seleziona il tipo id cliente che intendi creare:<br><br>


<input type="radio" id="clientiType" name="clientiType" value="azienda">&nbsp;&nbsp;Azienda &nbsp;&nbsp;&nbsp;

<input type="radio" id="clientiType" name="clientiType" value="privato">&nbsp;&nbsp;Privato<br>

<script>

	$(':radio[name="clientiType"]').click(function(){

		var valore=$(this).val();

		if(valore=="azienda")

		{

			$.ajax({

				url:'<?php echo Yii::app()->createUrl('azienda/ajaxcreate'); ?>',

				success:function(res)

				{

					

					$('<span>'+res+'</span>').appendTo('#content');

					

				}

			})

		}

	});

	

</script>

e in AziendaControlle.php




	public function actionAjaxcreate(){

		$model=new Azienda;

		$this->render('_form',array('model'=>$model));

	}

ma naturalmente in questo modo non funziona (altrimenti nn si spiegherebbe questo post :D ). In realtà non è propriamente vero che non funziona, ma non è quello che vorrei. Infatti facendo in questo modo mi viene proprio ricaricata la pagina azienda/create con tanto di maincontent header etc etc, io voglio solo il content che nello

specifico sarebbe il form di creazione del modello.

p.s. so perfettamente che il metodo da me scritto è un override delle funzionalità di yii, ma è solo una prova :D

Ringrazio anticipatamente tutti

Ok sarà l’ora tarda ma sono un fessacchiotto…

Come avrete capito ho risolto, ricordandomi che avevo già fatto una cosa del genere in un’altra applicazione.

Cmq se a qualcuno dovesse servire mi sono ricordato anche che su yiiplayground nella sezione ajax

c’è tutto scritto

Ma postaci la tua soluzione.

A me sembrava interessante capire ;)

Credo che devi restituire, come dati, il render del pezzo di pagina che ti serve (renderPartial).

L’azione nel controller diventa più o meno così:





    public function actionAjaxcreate(){ 


                $model=new Azienda; 


                echo CJSON::encode(array('div'=>$this->RenderPartial ('_form', array('model'=>$model), true);


                Yii::app()->end();

       }
5

C’è una ragione particolare per la quale hai convertito il form in un JSON?

6

Fammi pensare… fammi pensare…

Ah, si, perchè il codice che ho copio-incollato da un mio sorgente, prevedeva anche uno status di ritorno :smiley:





echo CJSON::encode(array('status'=>status, 

                         'div'=>$this->renderPartial ('_form', array('model'=>$model), true)

                  ));

(mancava anche qualche parentesi)

Quindi, se non serve uno status, dovrebbe essere sufficiente un semplice $this->renderPartial (BLA BLA BLA…

Giusto o mio sommo?

scusate la non celerità nella risposta ma sono stato senza internet per qualche giorno.

Comunque la soluzione che ho adottato è simile a quella di niconapoli

la mia pagina clienti.php adesso è così




<?php echo CHtml::ajaxLink(

	'<input type="radio" id="clientiType" name="clientiType" value="azienda">&nbsp;&nbsp;Azienda &nbsp;&nbsp;&nbsp;',

	array('azienda/ajaxcreate'), // the URL for the AJAX request. If empty, it is assumed to be the current URL.

	array(

		'update'=>'#req_res'

	),

	array("style"=>'text-decoration:none;color:#555;')

);

?>

<?php echo CHtml::ajaxLink(

	'<input type="radio" id="clientiType" name="clientiType" value="privato">&nbsp;&nbsp;Privato &nbsp;&nbsp;&nbsp;',

	array('azienda/ajaxcreate'), // the URL for the AJAX request. If empty, it is assumed to be the current URL.

	array(

		'update'=>'#req_res',

		

		

	),

	array(

	"style"=>'text-decoration:none;color:#555;')

);

?>

mentre nel controller ho semplicemente usato il renderPartial così




	public function actionAjaxcreate(){

		$model=new Azienda;


		$this->renderPartial('ajaxcreate', array('model'=>$model));


		Yii::app()->end();

	}

ovviamente in ajaxcreate ho messo il form che mi serve in questo modo

Se devi stampare dell’HTML puoi usare la renderPartial. Se devi stampare un JSON usi CJSON::encode.
