Smarty {foreach}, {foreachelse}

{Foreach} and {foreachelse} are used to access the associated array like the sequential number array.

Attribute Name

From: The array for loop access
Item: variable name of the current element
Key: The variable name of the current key name.
Name: name of the foreach loop used to access the foreach attribute
{Foreach from = $ variable item = item key = key name = name}

{$ Variable | @ count} // gets the length of the loop array

{$ Smarty. foreach. name. index} // returns the subscript of the array element of the current loop, starting with 0.

{$ Smarty. foreach. name. iteration} // gets the number of cycles, starting with 1

{$ Smarty. foreach. name. first} // when it is true, mark the first execution of the loop

{$ Smarty. foreach. name. last} // when it is true, mark the last execution of the loop

{$ Smarty. foreach. name. show} // whether the current display is displayed

{$ Smarty. foreach. name. total} // number of cycles

{/Foreach}

Foreach source) (performance indicator, iteration, first, last, display, overall.
<? Php
$ Arr = array (1000,100 1, 1002 );
$ Smarty-> assign ('myarray', $ arr );
?>

Template to output $ myArray in an un-ordered list

<Ul>
{Foreach from = $ myArray item = foo}
<Li >{$ foo} </li>
{/Foreach}
</Ul>
 

The above example will output:

<Ul>
<Li> 1000 </li>
<Li> 1001 </li>
<Li> 1002 </li>
</Ul>
 
 
Example 7-6. Demonstrates the item and key attributes

<? Php
$ Arr = array (9 => 'tennis ', 3 => 'canonicalization', 8 => 'coding ');
$ Smarty-> assign ('myarray', $ arr );
?>

Template to output $ myArray as key/val pair, like PHP's foreach.

<Ul>
{Foreach from = $ myArray key = k item = v}
<Li >{$ k }:{$ v} </li>
{/Foreach}
</Ul>
 

The above example will output:

<Ul>
<Li> 9: Tennis </li>
<Li> 3: padding Ming </li>
<Li> 8: Coding </li>
</Ul>
 
 
Example 7-7. {foreach} with associative item attribute

<? Php
$ Items_list = array (23 => array ('no' => 2456, 'label' => 'salad '),
96 => array ('no' => 4889, 'label' => 'cream ')
);
$ Smarty-> assign ('items ', $ items_list );
?>

Template to output $ items with $ myId in the url

<Ul>
{Foreach from = $ items key = myId item = I}
<Li> <a href = "item. php? Id = {$ myId} ">{$ I. no }:{$ I. label} </li>
{/Foreach}
</Ul>
 

The above example will output:

<Ul>
<Li> <a href = "item. php? Id = 23 "> 2456: Salad </li>
<Li> <a href = "item. php? Id = 96 "& gt; 4889: Cream </li>
</Ul>
 
 
Example 7-8. {foreach} with nested item and key

Assign an array to Smarty, the key contains the key for each looped value.

<? Php
$ Smarty-> assign ('contacts', array (
Array ('phone' => '1 ',
'Fax' => '2 ',
'Cell '=> '3 '),
Array ('phone' => '2014-555 ',
'Fax' => '2017-555 ',
'Cell '=> '2017-760 ')
));
?>

The template to output $ contact.

{Foreach name = outer item = contact from = $ contacts}
<Hr/>
{Foreach key = key item = item from = $ contact}
{$ Key }:{ $ item} <br/>
{/Foreach}
{/Foreach}
 

The above example will output:

<Hr/>
Phone: 1 <br/>
Fax: 2 <br/>
Cell: 3 <br/>
<Hr/>
Phone: 555-4444 <br/>
Fax: 555-3333 <br/>
Cell: 760-1234 <br/>
