    <p>I’m beginner in Magento and I’m with a QuickCheckout Form, where I need to validate the e-mail field. </p> <p>When the user put the e-mail on the field I need to search in the database (table customer_entity) the e-mail dynamically, without refresh </p> <p>I have code using Ajax.Request that works to validate the writing of e-mail using regular expressions </p> <pre><code>function validar_email() { local = "billing"; var urlAjax = location.href; var validarUrl = /^https:\/\//; if ( urlAjax.match( validarUrl ) ) { urlAjax = '&lt;?php echo Mage::getBaseUrl("link", true)."ajaxend/ajax" ?&gt;'; } else { urlAjax = '&lt;?php echo $this-&gt;getUrl("ajaxend/ajax") ?&gt;'; } new Ajax.Request( urlAjax, {method: 'POST', parameters: 'email='+$(local+':email').value, evalScripts: true, onLoading: function(transport) { $('load-email-'+local).innerHTML = 'Verificando E-mail'; }, onSuccess: function(transport) { var emailReg = /^[a-zA-Z0-9][a-zA-Z0-9\._-]+@([a-zA-Z0-9\._-]+\.)[a-zA-Z-0-9]{2}/; var emailValido = 'E-mail Válido'; var emailInvalido = 'E-mail Inválido, digite outro'; if( !emailReg.test($(local+':email').value)){ $('load-email-'+local).innerHTML = emailInvalido; } else { $('load-email-'+local).innerHTML = emailValido; } }, onComplete: function(transport) { }, onFailure: function() { /*document.getElementById("...").innerHTML = 'problemas...';*/ } }); } </code></pre> <p>I made two pieces of code to search in Database: Code 1: </p> <pre><code>$email = $_POST['email']; $resource = Mage::getSingleton('core/resource'); $readConnection = $resource-&gt;getConnection('core_read'); $table = $resource-&gt;getTableName('customer_entity'); $query = 'SELECT email FROM ' . $table . ' WHERE email = "'.$email.'";'; $sku = $readConnection-&gt;fetchAll($query); </code></pre> <p>Code 2 (only PHP): </p> <pre><code>$queryVerifEmail = ''; $queryVerifEmail .= ' SELECT email FROM customer_entity'; $queryVerifEmail .= ' WHERE email = "'.$email.'";'; $result = mysql_query($queryVerifEmail); </code></pre> <pre><code>if(mysql_num_rows($result) &gt; 1){ echo $email.' já existe na base!'; } else{ echo $email.'valido'; } </code></pre> <p>I tried to make referenced php files in the line </p> <pre><code>new Ajax.Request( "getEmail.php?", {method: 'GET', </code></pre> <p>And nothing works, but Ajax.Request is the only way to make working Inputs without refresh in Magento </p> <p>I want to have the best solution that you know, but I don´t want to buy or install new modules for it, I want a code solution, be in Ajax, JQuery or PHP. </p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
