for

Loop ViewHelper which can be used to iterate over arrays. Implements what a basic PHP foreach() does.

Examples

Simple Loop

<f:for each="{0:1, 1:2, 2:3, 3:4}" as="foo">{foo}</f:for>

Output:

1234

Output array key

<ul>
    <f:for each="{fruit1: 'apple', fruit2: 'pear', fruit3: 'banana', fruit4: 'cherry'}"
        as="fruit" key="label"
    >
        <li>{label}: {fruit}</li>
    </f:for>
</ul>

Output:

<ul>
    <li>fruit1: apple</li>
    <li>fruit2: pear</li>
    <li>fruit3: banana</li>
    <li>fruit4: cherry</li>
</ul>

Iteration information

<ul>
    <f:for each="{0:1, 1:2, 2:3, 3:4}" as="foo" iteration="fooIterator">
        <li>Index: {fooIterator.index} Cycle: {fooIterator.cycle} Total: {fooIterator.total}{f:if(condition: fooIterator.isEven, then: ' Even')}{f:if(condition: fooIterator.isOdd, then: ' Odd')}{f:if(condition: fooIterator.isFirst, then: ' First')}{f:if(condition: fooIterator.isLast, then: ' Last')}</li>
    </f:for>
</ul>

Output:

<ul>
    <li>Index: 0 Cycle: 1 Total: 4 Odd First</li>
    <li>Index: 1 Cycle: 2 Total: 4 Even</li>
    <li>Index: 2 Cycle: 3 Total: 4 Odd</li>
    <li>Index: 3 Cycle: 4 Total: 4 Even Last</li>
</ul>
