[PHPTAL] Imploding tal:attributesfrom source array

[Anton Andrievskij]

Ok, I see the problem. Probably you can try to use something like this then:

in your php code:

*$imgTag = '<img ';
foreach($attributes as $attrname => $attrvalue)
  $imgTag .= "$attrname=\"$attrvalue\" ";
$imgTag .= '/>';

$templateObject->imgTag = $imgTag;*

In your template:

*<span tal:replace="structure ${imgTag}"/>*
