Question

我正在尝试做这样的事情。如果大学选择不在下拉列表中，则用户选择＆＃34;其他＆＃34;现在，当他选择其他人时，他会移动到文本框并输入大学名称。

代码看起来像这样

                        <?php
                        if(isset($_POST['work_exp'])){
                        $inst_name = $_POST['inst_name'];
                        $inst_name2 = $_POST['inst_name2'];

                        if($inst_name =='Other')
                        {
                            $inst_name2:$inst_name;
                            echo $inst_name;
                        }

                            }
                        ?>

现在我遇到的挑战是它像这样返回错误

Parse error: syntax error, unexpected ':' in C:\xampp\htdocs\seekweb\brWeb.php on line 229

有什么想法吗？代码在这里工作得非常好

<!doctype html>
<html>
<head></head>
<title>test for dropdown</title>
<body>
<form name="school_form" id="school_form" method="post" action="test_form.php" />
<h1>Drop down Box test</h1>
School name :<select name="school" id="school" />
         <option selected="selected">Please Select School</option>
         <option>Catania School of Medicine</option>
         <option>J.M Hart University</option>
        <option>Beulah College of Business</option>
        <option>Crownay University</option>
        <option>Other</option>
        </select></br></p>
If Other, Please Enter Institution name : <input type="text" name="otherschool" id="otherschool" /></br></p>
<input type="submit" name="submit" value="Add School" />
</form>
</body>
</html>

<?php

if(isset($_POST['submit'])){
    $school = $_POST['school'];
    $otherschool = $_POST['otherschool'];

    if($school =="Other")
    {
        $otherschool:$school;
        echo $school;
    }

}

?>
