با سلام
چطوری میتونیم یه قالب سایت مثل قالب های وردپرس بسازیم؟؟
مثلا ببینید این template های وردپرس چند فایل هست
index.php
page.php
search.php
sidebar.php
single.php
archive.php
footer.php
header.php
و...
بعد اینا همه با توابعشون کنار هم میان و صفحه نمایش داده میشه ولی من نفهمیدم توابعش چطوری تعریف شدن ...
اگه میشه راهنمایی کنید که من نیاز زیادی به طراحی قابل به این صورت دارم
که مثلا اگه خواستم به sidebar چیزی اضافه کنم مجبور نشم به همه صفحات اضاففه کنم و فقط یه جا رو تغیر بدم
با تشکر
PHP include() Function
The include() function takes all the content in a specified file and includes it in the current file.
If an error occurs, the include() function generates a warning, but the script will
continue execution.
Example 1
Assume that you have a standard header file, called "header.php". To include the header file in a page, use the include() function:
<html>
<body>
<?php include("header.php"); ?>
<h1>Welcome to my home page!</h1>
<p>Some text.</p>
</body>
</html>
Example 2
Assume we have a standard menu file, called "menu.php", that should be used on all pages:
<a href="/default.php">Home</a>
<a href="/tutorials.php">Tutorials</a>
<a href="/references.php">References</a>
<a href="/examples.php">Examples</a>
<a href="/about.php">About Us</a>
<a href="/contact.php">Contact Us</a>
All pages in the Web site should include this menu file. Here is how it can be done:
<html>
<body>
<div class="leftmenu">
<?php include("menu.php"); ?>
</div>
<h1>Welcome to my home page.</h1>
<p>Some text.</p>
</body>
</html>
If you look at the source code of the page above (in a browser), it will look like this:
<html>
<body>
<div class="leftmenu">
<a href="/default.php">Home</a>
<a href="/tutorials.php">Tutorials</a>
<a href="/references.php">References</a>
<a href="/examples.php">Examples</a>
<a href="/about.php">About Us</a>
<a href="/contact.php">Contact Us</a>
</div>
<h1>Welcome to my home page!</h1>
<p>Some text.</p>
</body>
</html>
PHP require() Function
The require() function is identical to include(), except that it handles errors differently.
If an error occurs, the include() function generates a warning, but the script will continue execution. The require() generates a fatal error, and the script will stop.
Error Example include() Function
<html>
<body>
<?php
include("wrongFile.php");
echo "Hello World!";
?>
</body>
</html>
Error message:
Warning: include(wrongFile.php) [function.include]:
failed to open stream:
No such file or directory in C:\home\website\test.php on line 5
Warning: include() [function.include]:
Failed opening 'wrongFile.php' for inclusion
(include_path='.;C:\php5\pear')
in C:\home\website\test.php on line 5
Hello World! Notice that the echo statement is executed! This is because a Warning does not stop the script execution.
Error Example require() Function
Now, let's run the same example with the require() function.
<html>
<body>
<?php
require("wrongFile.php");
echo "Hello World!";
?>
</body>
</html>
Error message:
Warning: require(wrongFile.php) [function.require]:
failed to open stream:
No such file or directory in C:\home\website\test.php on line 5
Fatal error: require() [function.require]:
Failed opening required 'wrongFile.php'
(include_path='.;C:\php5\pear')
in C:\home\website\test.php on line 5 The echo statement is not executed, because the script execution stopped after the fatal error.
It is recommended to use the require() function instead of include(), because scripts should not continue after an error.
شما هر قسمت از صفحه رو بطور جدا می نویسید بعد با تابع include فراخوانی مکنید
چند تا مثال بالا واستون گذاشتم امیدوارم بکارتون بیاد
موفق باشید
