How do I display data from my table in the magento frontend?

Question

I'd like to display data from the database table on my frontend screen, I'm trying this way:

Teste/Cadastro/Block/Tabela.php

<?php
class Teste_Cadastro_Block extends Mage_Core_Block_Template
{
 public function getContent()
 {
 $cadastroModel = Mage::getModel('cadastro/cadastro');
 $collections = $cadastroModel->getCollection();
 foreach($collections as $collection)
 {
 print_r($collection->getdata(''));
 }
?>

default/template/cadastro/cadastro.phtml

...
 <div>
 <?php echo $this->getContent(); ?>
 </div>
...

And in my config.xml I have the declared block.

Does this have to be done through a block or even an action?

Answer 1

Use your model like that sample:

$cadastroModel = Mage::getModel('cadastro/cadastro');
$collections = $cadastroModel->getCollection()
 ->load();
foreach($collections as $collection){
 print_r($collection->getdata());
 }

• Gustavo Souza: It did not work, it only worked when I called directly in my phtml, but it is not the most correct way to do it, I will do all my phtml to analyze better
• Gustavo Souza: I think it's a mistake at the time of "pulling" or file to phtml, since it directly in phtml has effect, only that when I pull the file by <? Php echo $ this-> getCollection (); ?> It has no effect ..
• Gustavo Souza: I solved the error, in my xml I was setting as core / template and was not using my block "cadastro/tabela", thank you!
