Posted: Thu Sep 18, 2003 3:18 am Post subject: Short cuts for 'checked' and 'selected' and booleans |
|
|
I've been trying to think of clean shortcuts to handle generating selected and checked phrases + handle simple displaying of text pivoted around a boolean.
For example:
Code: |
<input type=checkbox name=fred value=3 {if $selected eq 3}checked{/if}>
<option value=3 {if $selected eq 3}selected{/if}>
$name {if $access}has access.{else}does not have access.{/if}
|
Here's my best thought so far:
Code: |
<input type=checkbox name=fred value=3 {$selected|asCheckedIf:3}>
<option value=3 {$selected|asSelectedIf:3>
$name {$access|asEither:has access.:does not have access.}
|
They don't feel entirely comfortable though. Just hoping to bounce the idea of others to see if a more natural way can (has) been found.
Here's the code for the modifiers .. not exactly rocket science But to save people typing if interested:
Code: |
#
# Modifier: asEither - shows a boolean as either of the two supplied values
# depending on whether the boolean is true or false
#
function smarty_modifier_asEither($ysnCond, $strTruePhrase, $strFalsePhrase="") {
if($ysnCond) return $strTruePhrase;
return $strFalsePhrase;
}
#
# Modifier: asCheckedIf - shows checked if modified variable equals supplied variable
#
function smarty_modifer_asCheckedIf( $mixSelected, $mixValue ) {
if( $mixSelected == $mixValue ) return " checked";
else return "";
}
#
# Modifier: asSelectedIf - shows selected if modified variable equals supplied variable
#
function smarty_modifer_asSelectedIf( $mixSelected, $mixValue ) {
if( $mixSelected == $mixValue ) return " selected";
else return "";
}
$smarty->register_modifier( "asEither", "smarty_modifier_asEither" );
$smarty->register_modifier( "asCheckedIf", "smarty_modifier_asCheckedIf" );
$smarty->register_modifier( "asSelectedIf", "smarty_modifier_asSelectedIf" );
