How to call php files from static html, _PHP tutorial
Static html method of calling php files,
It seems that the php file cannot be called directly in the static page, but you can use the js calling method to call the php file. Of course, you can also use ajax to call the php file. Let me introduce it to you below:
Example A simple example to illustrate:
If you use the following call in page a.html, you can pass the action=test parameter to b.php.
Javascript code
There is this piece of PHP code in b.php:
<?php
$action=$_GET['action'];
echo "document.write('".$action."');n";
?>
When the a.html file is executed, the b.php file will be called, and the output of the b.php file will be executed as a JS statement. The content is the value of the parameter action passed by JS, which is accepted in the PHP file. The value of the passed action.
The load function of jquery is a call that requests another file and loads it into the current DOM
1. Load a php file, which does not contain passed parameters
$("#myID").load("test.php");
2. Load a php file, which contains a passing parameter
$("#myID").load("test.php",{"name" : "Adam"});
3. Load a php file that contains multiple passed parameters. Note: Separate parameters with commas
$("#myID").load("test.php",{"name" : "Adam" ,"site":www.shouce.ren});
//The imported php file contains A passing parameter, similar to: test.php?name=Adam&site=www.shouce.ren
4. Load a php file that uses an array as a passing parameter
$("#myID").load("test.php",{'myinfo[]', ["Adam", www.shouce.ren});
//The imported php file contains a Array parameters are passed.
1 Call the PHP file using JS and get the value in php
Give a simple example to illustrate:
For example, in page a.html, use the following sentence to call:
<script type="text/javascript" src="b.php?action=test"></script> <script type="text/javascript" > alert(jstext); </script>
There is this piece of PHP code in b.php:
When the a.html file is executed, the b.php file will be called, and the output of the b.php file will be executed as a JS statement, so a prompt box will pop up here with the value of the JS variable jstext. That is the value assigned to jstext in the PHP file.
Summary:
Use JS to call the file in HTML to call the PHP file, and the output of the PHP file will be used as JS code by the calling page.
2 php calls the value in js
There is such a piece of code in the z.php page:
document.write(url) "; echo $key; ?>
3 php calls methods (functions) in js
< ;?php echo ""; ?>
4 JS calls PHP variables
(1)
$userId=100;
?> <script><br />var userId;<br />userId=document.getElementByIdx_x_x_x("userId").value;<br /> alert (userId);<br /></script>
(2)
$url = 'changed URL'; //Define variables
?>
5 -------------------------------
6 The js and php written by yourself call each other
1.php content:
<?php
//echo "<script LANGUAGE='javascript'>alert('$php变量');</script>"; //最简单的php调用js
//echo "<a href=#><img width=50 src='$fruit_pic_array[$i]' onMouseOver=’javascript:a();‘></a>";
//echo "<a href='3.php'>aaaa</a>"; //php中超链接
//echo "<script type='text/javascript' language='javascript'>phpmake('PHP建站学习笔记网');</script>"; //有时候需要在PHP执行过程中，需要调用JavaScript自定义函数(验证时出错)
echo "function ok(msg){alert(msg);}";
?>
