else
The Else tag always occurs within an If tag block.
Often you'd want to execute a certain set of statements when a given condition is met and a different set when the condition is not met.
Else provides this capability by extending the If tag. It does so by delimiting statements that will be executed when the condition given to the if does not evaluate to true.
For example -
<cms:if my_var == 'hello' >
<h3> Hello </h3>
<cms:else />
<h3> Don't know what it is </h3>
</cms:if>
In the snippet above, if variable 'my_var' contains 'hello', all the statements within the if tag block upto the else tag will be executed. In case 'my_var' contains any other value, all the statements within the if tag block starting from the else tag upto the end tag of if, will be executed. (In our example there are only single statements for both conditions but there can be any number of them).
Notice that the else tag is a self closing tag.
In cases where there are more than two outcomes of the condition, the else block can be made to contain another nested if block -
For example, here is a snippet that shows the stage of life by evaluating the variable 'age'.
<cms:if age lt '1' >
<h3>Infant</h3>
<cms:else />
<cms:if (age ge '1') && (age lt '3') >
<h3>Toddler</h3>
<cms:else />
<cms:if (age ge '3') && (age lt '5') >
<h3>Preschooler</h3>
<cms:else />
<cms:if (age ge '5') && (age lt '11') >
<h3>School Age</h3>
<cms:else />
<cms:if (age ge '11') && (age lt '13') >
<h3>Preteen or Tween</h3>
<cms:else />
<cms:if (age ge '13') && (age lt '20') >
<h3>Teen</h3>
<cms:else />
<h3>Adult</h3>
</cms:if>
</cms:if>
</cms:if>
</cms:if>
</cms:if>
</cms:if>
