Read-Only Properties Cannot Be Exposed by XML Web Services

It seems this is by design. The workaround would be to create an empty setter for it.

$username = new Zend_Form_Element_Text('username');
$username->setLabel('Username')
->setRequired(true)
->addFilter('StripTags')
->addFilter('StringTrim')
->addValidator('NotEmpty', true, array(
     'messages' => array(
          'isEmpty' => 'Username is required'
     )
  ))
->addValidator('Alnum', false, array(
     'messages' => array(
          'notAlnum' => 'Use only letters and numbers'
     )
  ));

The solution, given by Matthew Weier O’Phinney,  was found in the following thread:

Form Validation Messages

how to set error message for Required form validator?

Using Zend Framework and setting a Zend_Form_Element form field to be required, how do I change the validator used to ensure that the element is not blank

Zend_Form_Element NotEmpy validation when required is set to true

The validation failure message keys, i.e. isEmpty, notAlnum, can be found in the API Docs or by directly reading the validation class file in the library/Zend/Validate folder.

Can’t execute subsequent query after multiple queries from same Pdo_Mysql->exec() call

Can’t execute multiple stored procedures with Pdo_Mysql

Using the following code found in the Zend Framework Quickstart: Create a Model and Database Table

// this block executes the actual statements that were loaded from 
// the schema file.
try {
    $schemaSql = file_get_contents('./schema.sqlite.sql');
    // use the connection directly to load sql in batches
    $dbAdapter->getConnection()->exec($schemaSql);
    echo PHP_EOL;
    echo 'Database Created';
    echo PHP_EOL;

    if ($withData) {
        $dataSql = file_get_contents('./data.sqlite.sql');
        // use the connection directly to load sql in batches
        $dbAdapter->getConnection()->exec($dataSql);
        echo 'Data Loaded.';
        echo PHP_EOL;
    }

} catch (Exception $e) {
    echo 'AN ERROR HAS OCCURED:' . PHP_EOL;
    echo $e->getMessage() . PHP_EOL;
    return false;
}

Note that $dbAdapter->getConnection()->exec() gets called twice.

I encountered this issue when calling Pdo_Mysql->exec() or in the Zend Framework calling $dbAdapter->getConnection()->exec($schemaSql) one after the other.

One way to prevent the error was to call $dbAdapter->closeConnection() after each exec call. Another way I worked around this problem was to just execute the $schemaSql and the $dataSql in one exec call like below;

$schemaSql = file_get_contents('schema.sql', 1);
$dataSql = file_get_contents('data.sql', 1);
// use the connection directly to load sql in batches
$dbAdapter->getConnection()->exec($schemaSql . $dataSql);
