Question

<?php 

   if(isset($_POST['submit'])){
      // Here the code captures the inputs that entered. 
        Based on the inputs the script shows the associated information.
}

    <form method="POST">
    <input type="text" name="postc">
    <input type="text" name="nr">
    <button name="submit">Send</button>
    </form>

如何检查两个输入是否已填满，以及是否填充它们会自动加载PHP代码以获取数据。 （我是初学者）

我希望我解释得对！

Answer 1

我建议如下：

<强> HTML

<form method="POST" name="myForm" action="page.php">
    <input type="text" name="postc" onchange="submitForm()">
    <input type="text" name="nr" onchange="submitForm()">
</form>

<强>的Javascript

只要您填写表单输入，就会调用此函数。它提供了获取输入值并仅在填写所有（在本例中）输入时动态提交表单。

function submitForm() {
    var postc = document.forms["myForm"]["postc"].value;
    var nr = document.forms["myForm"]["nr"].value;

    if (postc != "" && nr != "")
        document.myForm.submit();
}

修改

这是一个完整的工作示例

<!DOCTYPE html> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"> <title>Your title</title> <script> function submitForm() { var postc = document.forms["myForm"]["postc"].value; var nr = document.forms["myForm"]["nr"].value; if (postc != "" && nr != "") { document.myForm.submit(); } } </script> </head> <body> <form method="POST" name="myForm" action="#"> <input type="text" name="postc" onchange="submitForm()"> <input type="text" name="nr" onchange="submitForm()"> </form> <?php if(isset($_POST['postc'])){ echo "postc value: " . $_POST['postc'] . '<br />'; echo "nr value: " . $_POST['nr']; } ?> </body> </html>
