Search mysql database with php with multi-level

Navigation

I am trying to perform the following query in the database, through an html form, but in php I am only able to fetch all the data from my table. In case the user would choose the type of filter and would be made a query in the database, I am using only one table in my database.

                               

     <form action="busca_filtro.php" method="GET">
         Data:
        <td align="left">
            <input name="tbxDe" type="text" value="13/05/2015" maxlength="10" id="tbxDe" style="height:23px;width:120px;">
            &nbsp;até
            <input name="tbxAte" type="text" value="14/05/2015" maxlength="10" id="tbxAte" style="height:23px;width:125px;">
            &nbsp;
        </td>
        <br><br>

Try building the query. Like this: 

<?php
$sql  = "SELECT ";
$sql .= isset($_GET['tipoManifestacao']) ? 'tipoManifestacao' :
        isset($_GET['concessionaria']) ? 'concessionaria' : 
        isset($_GET['status']) ? 'status' : 
        isset($_GET['dataAtendimento']) ? 'dataAtendimento' : '*';
$sql .= ' FROM tb_manifestacoes'

?>

From here the query data recovery follows.

The statement I put above works is a string of ifs and elses (only with other operators), selecting everything if no type is selected.

I am assembling a check before to know the options that user chose following the start of the verification: 

    if(!empty($tipoManifestacao AND $dataAtendimento AND $concessionaria AND $status AND $dataAtendimento))
        echo "Todos preenchidos";
    elseif(!empty($tipoManifestacao AND $dataAtendimento AND $concessionaria AND $dataAtendimento AND empty($status))){
        echo "Status Vazio";
    }
    elseif(!empty($tipoManifestacao AND $dataAtendimento AND $status AND $dataAtendimento AND empty($concessionaria))){
        echo "Concessionaria vazio";
    }
    elseif(!empty($dataAtendimento AND $status AND $dataAtendimento AND empty($tipoManifestacao))){
        echo "Tipo Manifestacao vazio";
    }
    elseif(!empty($tipoManifestacao AND $status AND $tipoManifestacao AND empty($dataAtendimento))){
        echo "Prazo vazio";
    }
    elseif(empty($tipoManifestacao AND $concessionaria AND $status AND $dataAtendimento)){
        echo "Todos vazios";
    }
