I define an array in my extensions setup.txt typoscript like so:
settings{
halls {
0 = Default
1 = Mississauga
2 = Halifax
3 = Niagara Falls
4 = Oakville
5 = Pickering
}}
how in my fluid template can I find the length of the halls array? I want an if condition to do one thing if length is greater than 1 and another if not.
I am using typo3 v4.5.32 with extbase 1.3.
Thank you.
I tried this but it puts out two <th>
tags instead of just one. The first if is meant to prove that there is more than one element, the next is meant to print out a <th>
only if it is the first element.
<f:for each="{settings.halls}" as="hall" key="number" iteration="itemIteration">
<f:if condition="{itemIteration.isFirst != itemIteration.isLast}">
<f:if condition="{itemIteration.index == 0}">
<th>
<f:translate key="tx_bpscoupons_domain_model_coupon.hall" />
</th>
</f:if>
</f:if>
</f:for>
Why?
UPDATE: here is my work around for a lack of "is array length > 1" ferature in fluid
<f:for each="{settings.halls}" as="hall" key="number" iteration="itemIteration">
<f:if condition="{itemIteration.isFirst}">
<f:then>
<f:if condition="{itemIteration.isLast}">
// if both first and last there is only one so skip
</f:if>
</f:then>
<f:else>
<f:if condition="{itemIteration.isLast}">
//if there is more than one element in halls then eventually you'll get here once so print out th tags
<th>
<f:translate key="tx_bpscoupons_domain_model_coupon.hall" />
</th>
</f:if>
</f:else>
</f:if>
</f:for>
and to print out data:
<f:for each="{settings.halls}" as="hall" key="number" iteration="itemIteration">
<f:if condition="{itemIteration.isFirst}">
<f:then>
<f:if condition="{itemIteration.isLast}">
<f:then>
</f:then>
<f:else>
<f:if condition="{number} == {coupon.hall}">
<td>{hall}</td>
</f:if>
</f:else>
</f:if>
</f:then>
<f:else>
<f:if condition="{number} == {coupon.hall}">
<td>{hall}</td>
</f:if>
</f:else>
</f:if>
</f:for>
ugly but seems to work.
UPDATE 2 : DOH!!! I missed total, just what I needed but I was looking for length or count, so this code is what I want:
<f:for each="{settings.halls}" as="hall" key="number" iteration="itemIteration">
<f:if condition="{itemIteration.total} > 1">
<f:if condition="{itemIteration.isLast}">
<th><f:translate key="tx_bpscoupons_domain_model_coupon.hall" /></th>
</f:if>
</f:if>
</f:for>
