如何进行相对搜索（由用户提供）

I have a lot of checkboxs like those :

The user will check one param of each checkbox to make the search.

How can I do that relative search informed by the user ? Isn't obligatted to select one of each checkbox.

My JS:

var checkeds = new Array();
$("input[name='marcar[]']:checked").each(function (){
    checkeds.push( $(this).val());
});
var obj = $("#paramsPesquisa");
if($(obj).find("input[id='cd_seq_pedido']:checked").length > 0){
    var cd_seq_pedido = $(obj).find("input[id='cd_seq_pedido']:checked").val();
}else{
    var cd_seq_pedido = "";
}

My Ajax:

$.ajax({
    type: "POST",
    url: "/pedidoOnline/index.php/Pedidos/checkbox_marcados",
    data: {
        'marcar':checkeds,
        'cd_seq_pedido': cd_seq_pedido,
        'cd_pedido': cd_pedido
    },
    success: function(data){
        console.log(data);
    } 
});

On my controller, how can I make this query ?

$pesquisa = $this->PesquisaPedOnline->find('all', array(
    'fields' => array('cd_seq_pedido', 'cd_pedido', 'ds_cpl_tamanho_interno'),
    'conditions' => array(?????)
));

If need more information, I'll put, sorry if I couldn't explain clearly.

When you build the conditions array in Cake you need to specify what field each of the checkbox values corresponds with. For example:

$conditions = array(
    'ModelName.fieldname1' => 'value1', // a single checkbox value
    'ModelName.fieldname2' => 'value2, value3, value4', // multiple checkbox values
    // etc...
);

To be able to construct the $conditions array like this you need to pass more information to the controller in your ajax call. I would suggest constructing a JSON object so you can build something like {'fieldname1':'value1, value2'}.

Also you may want to consider how to remove items that the user unchecks.

Use the search plugin: https://github.com/cakedc/search

The name is a little misleading, it actually implements the PRG pattern and deals with the transformation of a POST request into search conditions.

This is a lot more clean than doing a huge amount of if-else checks on the POST data manually. Just take a look at the examples and tutorials, it's pretty straight forward.
