TYPO3 href not working

Question

I am quite new to TYPO3, I am inspecting a code for errors and I saw a non working href. the inspection in the browser shows empty href :

<a class="download" target="_blank" title="Initiates file download" href=""> here..</a>

The code is :

<a class="download" target="_blank" title="Initiates file download" href="{location.pdf.originalResource.publicUrl}"><f:translate key="tx_locations_domain_model_location.here" />..</a>

I don't understand this location.pdf.originalResource.publicUrl !! When I display {location} I get : Locations\Locations\Domain\Model\Location:102 I can't find such path in my folders !! What am I missing !!

When I make

<f:debug>{location}</f:debug>

I see : pdf => NULL , how can I fix it, in my backend I select a PDF and saved. no error message UPDATE: My Pdf field is int(11) unsigned, Here is my TCA (typo3conf/ext/locations/Configuration/TCA/Location.php)

$GLOBALS['TCA']['tx_locations_domain_model_location'] = array(
....
    'columns' => array(
....
    'pdf' => array(
        'exclude' => 1,
        'label' => 'LLL:EXT:locations/Resources/Private/Language/locallang_db.xlf:tx_locations_domain_model_location.pdf',
        'config' => array (                             
            'type' => 'group',
            'internal_type' => 'file',
            'allowed' => $GLOBALS['TYPO3_CONF_VARS']['GFX']['imagefile_ext'],
            'max_size' => $GLOBALS['TYPO3_CONF_VARS']['BE']['maxFileSize'],
            'uploadfolder' => 'uploads/pics',

            'size' => 1,
            'minitems' => 0,

Answer 1

Your model Location.php file. You can't define getPdf() method only use set method. Please define first getPdf() method in your Location.php file.

Like this.

 /**
 * Returns the pdf
 *
 * @return \TYPO3\CMS\Extbase\Domain\Model\FileReference $pdf
 */
public function getPdf() {
    return $this->Pdf;
}

After you can debug your .html file like this <f:debug>{_all}</f:debug> and see the debug output.

Answer 2

You don't have to use in Fluid things like <a href=""/>, you can find the <f:link..>, <f:uri..>,etc, in fluid documentation for generating links.

But there for file downloading you have to use this viewhelper. You have to know only the uid of the file. In your case {location.pdf.uid} Be sure that you have indexed files before use it.

<v:resource.file additionalAttributes="{foo: 'bar'}" data="{foo: 'bar'}" identifier="[mixed]" categories="[mixed]" treatIdAsUid="1" treatIdAsReference="1" as="NULL">
    <!-- tag content - may be ignored! -->
</v:resource.file>
