Hi i want to know how can i show an alert in cakephp with script...i have this form

<div class="soyaproductorcompras form">
 <h3>Registro de Compra de Grano </h3>
<?php echo $this->Form->create('SoyaProductorCompra');?>
    <fieldset>

        <?php 

        echo $this->Form->input('soya_proveedor_id', array( 'options' => $soyaproveedores,'empty' => '--Porfavor Seleccione Proveedor--','label' => 'Por Favor Seleccione a algun Proveedor de la lista' ));

        echo $this->Form->input('producto', array(
            'options' => array( 
                'GRANO DE SOYA' => 'Grano de Soya',
                'GRANO DE GIRASOL' => 'Grano de Girasol'
                ), 'label'=>'Tipo de Grano  '
        ));

        echo $this->Form->input('toneladas', array('label' => 'Cantidad en tonelada(s) métrica(s) del producto  (TM)','style'=>'width:500px; height:30px;','default'=>0));

        echo $this->Form->input('preciodolar', array(
            'label' => 'Precio en Dolares Americanos por tonelada métrica (TM / $us)',
            'style'=>'width:500px; height:30px;',
            'default'=>0));

        echo $this->Form->input('fecharegistro', array('dateFormat' => 'DMY', 'minYear' => date('Y')-3,
                                             'maxYear' => date('Y') + 1, 'label' => '<strong>Periodo al que corresponde la declaración jurada</strong>','empty'=>false, 'type'=>'date'));

?>
    </fieldset>
<?php echo $this->Form->end(); ?>
</div>

So i don't know how and where to put the script and how to call it...this form sends data for DB..that part is working good!...but my client want to see a miniscreen with a message like this "Are you sure you want to save this form??" and he click yes or no please help!!!

So write some javascript to intercept the form submission and show a confirmation box. This is not specific to CakePHP and can be done relatively easily. http://stackoverflow.com/questions/6515502/javascript-form-submit-confirm-or-cancel-submission-dialog-box — Jeremy Harris, May 28 '14 at 01:34

well my problem was solved with a lot of help from here...so my code change a little bit...y had only add my script at beggining of my view...

<script>
function show_alert()
{
   if (confirm("¿Esta seguro guardar el formulario?")) { return true; } 
   return false;
}
</script>

And in my form i change my submit like this,

echo $this->Form->submit('Agregar Existencia', array('class' => 'form-submit',  'title' => 'Presione aqui para agregar datos', 'onclick' => 'return show_alert();'));

Note that the function have this 'return' and ends in ';', if you doesn't put those things the code doesn't work... i hope my solution can helps!!

Create js file and put it in webroot/js folder
just link it with your view as follows
echo $this->Html->script('your_file_name'); 
function desired_fun_name()
{
alert();
}
and write your desired function and call it on onclick

as follows: echo $this->Form->submit('Agregar Existencia', array('class' => 'form-submit', 'title' => 'Presione aqui para agregar datos', 'onclick' => 'desired_fun_name()'));
