当我有自定义验证时，当我点击提交时，我无法运行我的 php 文件。当我在下拉框中选择其他时，会出现一个文本框。一旦我点击提交，它将不会运行我的 php 文件。如果我在没有此自定义验证的情况下在下拉列表中选择一个值，我的 php 文件将运行。

<body>
<form action="form-to-email.php" method="post" name="LeaveRequestPart1" id="LeaveRequestPart1">
    <table class="LeaveRequestPart1" align="center">

<tr>
    <td colspan="2"><font color="red">*</font>
        <label>Type of Leave</label>
            <select name="TypeOfLeave" id="TypeOfLeave" onchange =
           "if(this.value=='Other'{this.form['Other'].style.visibility='visible'}else {this.form['Other'].style.visibility='hidden'};">
                <option value="N/A"></option>                       
                        <option value="Vacation">Vacation</option>
                        <option value="Illness">Illness</option>

$headers .= "Reply-To: $to2 \r\n";

//Send the email!
mail($to,$Email_subject,$Email_body,$headers);

//done. redirect to thank-you page.
header('Location: form-end.html');


// Function to validate against any email injection attempts
function IsInjected($str)

检查页面是否抛出任何 javascript 错误。我可以在您的事件中看到一个错误onChange- 缺少右括号if。尝试

<select name="TypeOfLeave" id="TypeOfLeave" 
    onchange="
        if(this.value == 'Other') {
            this.form['Other'].style.visibility = 'visible';
        } else {
            this.form['Other'].style.visibility = 'hidden';
        }">

如果你也可以使用三元

onchange="this.form['Other'].style.visibility = (this.value == 'Other') ? 'visible': 'hidden';"
