If "$Bestellung->kBestellung|@intval" can't go below zero, you can write just that without any comparison.
And if that is a number, you don't need to waste CPU time applying @intval. |

| Then enable all php error messages and enable display_errors. |

If object or its property may not exist you should check it with isset()
| Code: | {if isset($Bestellung->kBestellung) && $Bestellung->kBestellung|intval > 0}
...
{/if} |

The use of @ at modifier has nothing to do with error suppression. Smarty2 used it to run modifiers on arrays. In Smarty3 this is a noop. |

Hm... I tried this, but it's still the same...
Btw. $Bestellung->kBestellung is set to 0... If it's set to 1 it works, no white page...
| Code: | {if isset($Bestellung->kBestellung)}
...
{/if} |

isset($Bestellung->kBestellung) alone does only check if the object and kBestellung property does exist. you template still may fail if kBestellung == 0.
Try this
| Code: | {if isset($Bestellung->kBestellung) && $Bestellung->kBestellungl > 0}
...
{/if} |

this doesn't work, too..
i still get the white page if $Bestellung->kBestellung is 0 or negative, if itīs 1 or greater, it works... I'm stumped...
this are the notices and warnings:

But there is no reference to the file (remarketing.tpl), the "isset($Bestellung->kBestellung) && $Bestellung->kBestellung > 0" statement is in. |

Are you sure that templates get recompiled after modification?
Is $smarty->compile_check == true ? which is the default setting.
You could try to clear the template_c and cache folder manually.
If you still get the error I suspect that the problem is not the {if} but somewhere else.
Does it run if you remove the {if} ... {/if} section? |

As i said, ist runs, except the value is 0 or lower...
I found out, that it even runs when I change the if statement to $Bestellung->kBestellung == 0 instead of > 0
May it be, that just the equation causes this problem? |

Just in case you copied and pasted my code: I had a typo.
| Quote: | | $Bestellung->kBestellungl > 0 |
Must be
| Quote: | | $Bestellung->kBestellung > 0 |

Which Smarty version do you use?
Set $smarty->debugging = true;
Check with it the assigned values. |

Thanks!
Version is 2.6.26
Because of the white page - i think- there is no debugging console with $smarty->debugging = true;
with $Bestellung->kBestellung = 1, the console shows that $Bestellung->kBestellung == 1
when I change the statement to "$Bestellung->kBestellung == 0" it all works fine, but i need it to "$Bestellung->kBestellung > 0" an this does not work
I post the complete "if":
| Code: | ...
{elseif $nSeitenTyp == 33 && isset($Bestellung->kBestellung) && $Bestellung->kBestellung > 0}
{assign var="setValue" value=$oPlugin_netzdingeDE_google_codes->oPluginEinstellungAssoc_arr.cEcommTotalValue}
{assign var="cArtNrString" value=""}
{foreach name=AktuellerArtikel from=$Bestellung->Positionen item=AktuellerArtikel}
{if $AktuellerArtikel->cArtNr != ''}
{if $smarty.foreach.AktuellerArtikel.iteration > 1}
{assign var="cArtNrString" value="$cArtNrString,"}
{/if}
{assign var="cArtNrString" value=$cArtNrString|cat:'"'|cat:$AktuellerArtikel->cArtNr|cat:'"'}
{/if}
{/foreach}
{assign var="ecomm_prodid" value="[$cArtNrString]"}
{assign var="ecomm_totalvalue" value=$Bestellung->$setValue}
{/if} |
remember this is working:
| Code: | | {elseif $nSeitenTyp == 33 && isset($Bestellung->kBestellung) && $Bestellung->kBestellung == 0} |

Ohh, Smarty 2 is outdated on no longer supported.
It's support of objects is very limited.
This workaround could work
| Code: | {assign name='foo' value=$Bestellung->kBestellung}
{if $foo > 0}
....
|
Currently we have already Smarty 3.1.21 .
It has very good support for objects besides all sort of other features.
I should have ask the version question much earlier, |
