how to access array form position dynamically in html/php form?

manpreet Best Answer 3 years ago

I am doing a little learning on php and and html using smarty to aid it. I am trying to build a very simple shop-alike list with a cart image that when it is clicked, it is supposed to return via form the info I want from that item, but I am failing to get the index of the items right....

This is the code relative to the loop inside the tlp (it is a HTML internally used by smarty):

{section name=i loop=$homeList}
     <div class="homemenu" align="right">
        <table class="menhome" border="0">
            
            <td width="102"><img src="{$homeList[i].img}"/>td>
            <td width="150">{$homeList[i].Nome} td>
            <td width="350">{$homeList[i].Descricao}td>
            <td width="80">{$homeList[i].Preco} €td>
            <td width="80">{$homeList[i].Disponiblidade}td>
            <form action="updatecart.php"  method="POST">
                <input type="hidden" name="usr[]" value="abobora">
                <input type="hidden" name="iditem[]" value="{$homeList[i].IDItem}">
                <input type="hidden" name="qta" value="1">
                <input type="hidden" name="index" value="1">
                <input type="image" name="submit" src="../images/carro.png" width="52" height="52"> 
            td>
            tr>
        table>
    div>
{/section}

and this is the code relative to the "experimental" php update:

require_once("functions.php");
var_dump($_POST);

and this is a sample var_dump output:

array
'usr' => 
    array
      0 => string 'abobora' (length=7)
      1 => string 'abobora' (length=7)
      2 => string 'abobora' (length=7)
      3 => string 'abobora' (
                                                

                                                                                                        
                                                    
                                                
                                                

                                                    

                                                        
                                                            0
                                                            views 

                                                            0
                                                                likes 
                                                            
                                                            

                                                            0
                                                            shares
