{while} loops in Smarty have much the same flexibility as PHP
while
statements, with a few added features for the template engine.
Every {while} must be paired with a matching
{/while}. All PHP conditionals and functions
are recognized, such as ||, or,
&&, and,
is_array(), etc.
The following is a list of recognized qualifiers, which must be separated from surrounding elements by spaces. Note that items listed in [brackets] are optional. PHP equivalents are shown where applicable.
| Qualifier | Alternates | Syntax Example | Meaning | PHP Equivalent |
|---|---|---|---|---|
| == | eq | $a eq $b | equals | == |
| != | ne, neq | $a neq $b | not equals | != |
| > | gt | $a gt $b | greater than | > |
| < | lt | $a lt $b | less than | < |
| >= | gte, ge | $a ge $b | greater than or equal | >= |
| <= | lte, le | $a le $b | less than or equal | <= |
| === | $a === 0 | check for identity | === | |
| ! | not | not $a | negation (unary) | ! |
| % | mod | $a mod $b | modulous | % |
| is [not] div by | $a is not div by 4 | divisible by | $a % $b == 0 | |
| is [not] even | $a is not even | [not] an even number (unary) | $a % 2 == 0 | |
| is [not] even by | $a is not even by $b | grouping level [not] even | ($a / $b) % 2 == 0 | |
| is [not] odd | $a is not odd | [not] an odd number (unary) | $a % 2 != 0 | |
| is [not] odd by | $a is not odd by $b | [not] an odd grouping | ($a / $b) % 2 != 0 |
Example 7.79. {while} loop
{while $foo > 0}
{$foo--}
{/while}
The above example will count down the value of $foo until 1 is reached.
