How can we separate Logic from presentation without using any temp开发者_JAVA技巧late engine (traditional php-not OOP) Thank in advance
Why not to use PHP itself as a template engine? It being used in the code I posted for your other question. Your program has to be split into 2 main sections: getting data and displaying data.
Each page have to have it's own template. In the code I posted there is 2 very simple templates, form.php
and list.php
just extend it with the whole site template, And you have done!
Here is a little more complex PHP template example:
<table border="0" cellpadding="2" cellspacing="0" width="600">
<? foreach ($data as $row): ?>
<tr bgcolor="#666699">
<td align=left>
<font color="white"><b><?=$row['name']?></b></font>
</td>
<td align=right><font color="white">
<?=$row['date'] ?>
</font></td>
</tr>
<tr bgcolor="f0f0f0">
<td colspan=2><?=$row['body'] ?></td>
</tr>
<? if ($row['answer']): ?>
<tr bgcolor="d3d3d3">
<td colspan=2 valign="top">
<table border="0" cellpadding="0" cellspacing="5">
<tr>
<td valign="top"><b>Answer: </b></td>
<td><?=$row['answer'] ?></td>
</tr>
</table>
</td>
</tr>
<? endif ?>
<? if($admin): ?>
<tr>
<td colspan=2>
<font size=-1>
<?=$row['id']?> - <?=$row['ip']?> - <?=$row['topic']?>
<? if($row['del']): ?>
<a href="/gb/?action=show&id=<?=$row['id']?>">show</a>
<? else: ?>
<a href="/gb/?action=hide&id=<?=$row['id']?>">hide</a>
<? endif ?>
<a href="/gb/?action=edit&id=<?=$row['id']?>">edit</a>
</font>
</td>
</tr>
<? endif ?>
<? endforeach ?>
</table>
And it is called like this
<?
//some code to get data
include 'tpl_top.php';
include 'tpl_list.php';
include 'tpl_bottom.php';
?>
Looks magnificent to me!
Dunno though, if it's what you're asking for :)
PHP itself can be used as a template engine. Just put all your logic before you output anything. Put simply:
- Process your input
- Assign all the dynamic data to be output to variables
- Run your view code. The view code may be in a separate file which you include.
- In the view, just use things such as
echo
andforeach
to output the data you put into variables in step 2.
