PHP only read the first value of input array dynamic created

Question

Sorry for the bad English, I'm still learning...

Well i have in HTML a table with only

<tr id="linha_1">
    <td><input type="text" name="nome_cor[]" value="" /></td>
    <td><input type="text" name="cod_cor[]" value="" /></td>
    <td><input type="file" name="img_cor[]" /></td>
    <td><input type="button" value="Remover" id="remove" onclick="$.removeLinha(this);" /></td>
</tr>

I also have a JS script that adds new rows to this table, this script copy the first line, so the user can add more colors...

$(document).ready(function()
{
    var row_limit = 0;
    $('#add').click(function()
    {
        var linha_total = $('tbody#repetir tr').length;
        if (row_limit == 0 || row_limit > linha_total)
        {
            var linha = $('tbody#repetir tr').html();
            var linha_total = $('tbody#repetir tr').length;             
            var linha_id = $('tbody#repetir tr').attr('id');                
            $('tbody#repetir').append('<tr id="linha_' + (linha_total + 1) + '">' + linha + '</tr>');
        }
        else
        {
         alert("Desculpe, mas você só pode adicionar até " + limite_linhas + " linhas!");
         }                      
});

Using malsup form plugin to send the data via post:

$("#send").click(function(event) {
    event.preventDefault();
    $("#form-tapete").ajaxForm({        
        // validation and progress bar (*not important to the question i think*)
    },
    url: 'dados-tapete.php',
    resetForm: false
 }).submit();

I'm trying to read this in PHP with this code:

for ($i=0; $i < sizeof($cod_cor); $i++)
{
    $path_cor = "catalogo/tapete/cor/";
    $path_cor = $path_cor.basename($_FILES["img_cor"]["name"][$i]); 
    if (!move_uploaded_file($_FILES["img_cor"]["tmp_name"][$i], $path_cor)) 
        die("Ocorreu um erro ao enviar a imagem, tente novamente!"); 
    $cor_img_name = "catalogo/tapete/cor/".$_FILES["img_cor"]["name"][$i]; 
    $cadastra_cores = $con->sql_query("INSERT INTO tape_cores VALUES ('$nome_tapete','$cod_cor[$i]','$nome_cor[$i]','$path_cor')"); 
}

The PHP script can read and send the values to the database, but only the first value... The rows that was added dynamically don't appear in the $_POST array...

I searched for this and found some asked questions here, but no solution...

Sorry for the bad English again, if you don't understand me I can try to explain in other words... thanks

show to javascript code which is generating the input fields, the input field should generate with the same parameters if you need a output in array like <input type="text" name="nome_cor[]" value="" /> — Muhammad

So how do you actually POST the data? You should show this code. — Mike Brant

Are you sure that your dynamic fields are truly get appended? And what is the value of sizeof($cod_cor) here? — MahanGM

I would use JQuery with something like this :

$.post( "test.php", $( "#testform" ).serialize() );

For Malsup JQuery, use formSerialize();

var queryString = $('#myFormId').formSerialize();  
$.post('myscript.php', queryString);

I'm sending the form with Malsup's jQuery form plugin, i have to change it?

I don't know Malsup, but regarding the doc seems possible and not so far away from the pure JQuery way : jquery.malsup.com/form/#api

i don't get problems to send the values via $_POST, the problem is im only sending the first value of the input arrays... thanks for the attention

If you add "echo $i;" in the for loop what result do you get ?

Shawii Over a year ago

the "echo $i;" returns 0
