form上传文件,如何弹出新窗口调用php处理,并返回原窗口?
情况是这样的,第一个窗口有一个form 用于上传文件。上传完文件后打开窗口二,用一个php去处理这个文件(比如说复制到某个位置),然后php要把这个文件的位置返回给窗口1。
窗口1:
窗品2:
php代码,调用窗口1中的insertText函数,把结果返回。
谁能给个办法?我现在用form action=‘a。php",结果不行,新的php窗口会把原来的窗口冲掉。我是想不动第一个窗口。
谢谢了,我搞了一天,找了各种资料。无奈基础不行,求各位大能帮忙啊~
------解决方案--------------------
ajax.
我记得jquery 有个上传的插件.
------解决方案--------------------
iframe无刷新上传文件是一种解决方法,当然还有其它的办法,关键在form标签的target属性,它会决定表单页面在哪里打开
- PHP code

看这个能帮上忙不。

在你上传的方法(a.php)中 加入
- PHP code
echo "<script>history.back();</script>"<br><font color="#e78608">------解决方案--------------------</font><br>你这样的话,还不如在第一个窗口中,点击弹出一个新窗口处理好上传文件后,再用JS window.opener把值返回之前窗口指定位置中。<br><br>版主说的是uploadify这个插件吧?<br><font color="#e78608">------解决方案--------------------</font><br>第二个窗口:<br><?php <br />……<br>echo '<script>window.opener.abc();</script>';<br>?><br><br>窗口1:<br>function abc() {<br>……<br>}<br><br>这样行不?<div class="clear"> </div>

PHP remains important in modern web development, especially in content management and e-commerce platforms. 1) PHP has a rich ecosystem and strong framework support, such as Laravel and Symfony. 2) Performance optimization can be achieved through OPcache and Nginx. 3) PHP8.0 introduces JIT compiler to improve performance. 4) Cloud-native applications are deployed through Docker and Kubernetes to improve flexibility and scalability.

PHP is suitable for web development, especially in rapid development and processing dynamic content, but is not good at data science and enterprise-level applications. Compared with Python, PHP has more advantages in web development, but is not as good as Python in the field of data science; compared with Java, PHP performs worse in enterprise-level applications, but is more flexible in web development; compared with JavaScript, PHP is more concise in back-end development, but is not as good as JavaScript in front-end development.

PHP and Python each have their own advantages and are suitable for different scenarios. 1.PHP is suitable for web development and provides built-in web servers and rich function libraries. 2. Python is suitable for data science and machine learning, with concise syntax and a powerful standard library. When choosing, it should be decided based on project requirements.

PHP is a scripting language widely used on the server side, especially suitable for web development. 1.PHP can embed HTML, process HTTP requests and responses, and supports a variety of databases. 2.PHP is used to generate dynamic web content, process form data, access databases, etc., with strong community support and open source resources. 3. PHP is an interpreted language, and the execution process includes lexical analysis, grammatical analysis, compilation and execution. 4.PHP can be combined with MySQL for advanced applications such as user registration systems. 5. When debugging PHP, you can use functions such as error_reporting() and var_dump(). 6. Optimize PHP code to use caching mechanisms, optimize database queries and use built-in functions. 7

The reasons why PHP is the preferred technology stack for many websites include its ease of use, strong community support, and widespread use. 1) Easy to learn and use, suitable for beginners. 2) Have a huge developer community and rich resources. 3) Widely used in WordPress, Drupal and other platforms. 4) Integrate tightly with web servers to simplify development deployment.

PHP remains a powerful and widely used tool in modern programming, especially in the field of web development. 1) PHP is easy to use and seamlessly integrated with databases, and is the first choice for many developers. 2) It supports dynamic content generation and object-oriented programming, suitable for quickly creating and maintaining websites. 3) PHP's performance can be improved by caching and optimizing database queries, and its extensive community and rich ecosystem make it still important in today's technology stack.

In PHP, weak references are implemented through the WeakReference class and will not prevent the garbage collector from reclaiming objects. Weak references are suitable for scenarios such as caching systems and event listeners. It should be noted that it cannot guarantee the survival of objects and that garbage collection may be delayed.

The \_\_invoke method allows objects to be called like functions. 1. Define the \_\_invoke method so that the object can be called. 2. When using the $obj(...) syntax, PHP will execute the \_\_invoke method. 3. Suitable for scenarios such as logging and calculator, improving code flexibility and readability.
