Hello,

I write on a snippet for revolution.
I can read the value of a TV from an specific dokument with this function:

$doc->getTVValue('docCount');

But what I need now is the opposite: I want write the value of the TV.

Have anyone a idea?

Hello

Try this :

/*set the TV value
$tv->setValue($tv, 'new value');

or maybe

/*set the TV value
$tv->setTVValue($tv, 'new value');

Don’t forget to save() after reset your TV...
Cheers

Hi Anso,

thank you for your reply.
I try this:

 $tv->setTVValue('docCount', 'new value');

(docCount ist the name of the TV)

I get an error like this:

Fatal error: Call to a member function setTVValue() on a non-object in www...

If you have :

$doc->getTVValue('docCount');

You can try this it should work I think

//get the value of the TV
$tv = $doc->getTVValue('docCount');

// set the value
$tv->setTVValue('docCount', 'new value');

$tv "stores" the TV value, then you can act on it...

I suppose it’s possible like that too :

setTVValue('$doc->getTVValue('docCount')','new value');

Hope this helps
Cheers

Hi,

both did not Work. I get an PHP error: "Call to a member function..."

Here is my complete Code:

// Get ID of current document:
$docID = $modx->resource->get('id');   

// Get title of current document:
$docTitle = $modx->resource->get('pagetitle');

// Get the value of the TV docCount:
$doc = $modx->getObject('modResource', $docID);
//echo $doc->getTVValue('docCount');

// Add 1 to the value of docCount and call it newValue:
$newValue = $doc->getTVValue('docCount') + 1;

To that point the code ist working.
$newValue is the value that I want to write into the TV docCount now.

I didn’t try this but I think it should work... Let me know

// get ID of the current document
$docID = $modx->resource->get('id');

// get the TV docCount in the current doc 
$tv = $modx->getObject('modTemplateVar',array('name'=>'docCount'));

// Add 1 to the value of docCount and call it newValue:
$newValue = $doc->getTVValue('docCount') + 1;

// Set the tv docCount with new value
$tv->setValue($docID, $newValue);
$tv->save();

Hope this helps...
Cheers

Hi Anso,

I try your example at I get an PHP error:

Fatal error: Call to a member function setValue() on a non-object in www....core/cache/elements/modsnippet/14.include.cache.php on line 20

That’s because it should be this:

// get the TV docCount in the current doc 
$tv = $modx->getObject('modTemplateVar',array('name'=>'docCount'));

// Add 1 to the value of docCount and call it newValue:
$newValue = $modx->resource->getTVValue('docCount') + 1;

// Set the tv docCount with new value
$tv->setValue($modx->resource->get('id'), $newValue);
$tv->save();

I tried this one and it works fine

<?php
// get ID of the current document
$docID = $modx->resource->get('id');
  $doc=$modx->resource;

// get the TV Color in the current doc
$tv = $modx->getObject('modTemplateVar',array('name'=>'Color'));

// Add 1 to the value of docCount and call it newValue:
$newValue = "red";

// Set the tv Color with new value
$tv->setValue($docID, $newValue);
$tv->save();
  $doc->save();
?>

Yep I’d forgot to declare "$doc=$modx->resource;" so my "$doc->getTVValue" cannot work of course !sorry for this...

The opposite for "getTVValue"
