isFieldError takes the full errorString, throws it away and then only
returns true or false; This means that the errors are not avilable to
you to display. strange that this is the case, i'm assuming its some
sort of bug, or something leftover as the code has switched between 2
designs.
I'm not a massively experienced baker, so i did the following.
change cake/libs/views/helpers/form.php
function generateInputDiv($tagName, $prompt, $required = false,
$errorMsg = null, $size = 20, $htmlOptions = null) {
$htmlAttributes = $htmlOptions;
$htmlAttributes['size'] = $size;
$str = $this->Html->input($tagName, $htmlAttributes);
$strLabel = $this->labelTag($tagName, $prompt);
$divClass = "optional";
if ($required) {
$divClass = "required";
}
$strError = "";
if ($this->isFieldError( $tagName )) {
$fieldErrorMessage = $this->getFieldError( $tagName );
$strError = $this->pTag('error', $fieldErrorMessage);
$divClass = sprintf("%s error", $divClass);
}
$divTagInside = sprintf("%s %s %s", $strError, $strLabel, $str);
return $this->divTag($divClass, $divTagInside);
}
see that it now includes a call to getFieldError()
this is a new function that I added which returns the actual error (in
fact, the mostly recently set error for a particular field, as cake
throws others away, afaict)
function getFieldError( $field ) {
return $this->Html->tagIsInvalid( $this->Html->model, $this->Html->field );
}
If a more experienced baker can improve this methodology, please do so.
