php - 以图像作为按钮的联系表单

Question

如何使按钮的图像完好无损，并且仍然发送邮件或清除表单？我正在尝试将图像用作此联系表中的按钮。一个按钮是清除表单，另一个按钮是将邮件发送到邮件 ID。

我的 php 编码是:

<?php
$submitted = FALSE;
if ($_POST['contact_form']) {
    $submitted = TRUE;  // The form has been submitted and everything is ok so far…
    $name = htmlspecialchars($_POST['name'], ENT_QUOTES);
    $email = htmlspecialchars($_POST['email'], ENT_QUOTES);
    $website = htmlspecialchars($_POST['website'], ENT_QUOTES);
    $message = htmlspecialchars($_POST['message'], ENT_QUOTES);
    if ($name == "") {
        // if the name is blank… give error notice.
        echo "<p>Please enter your name.</p>";
        $submitted = FALSE;  // Set this to FALSE so that it the message is not sent.
    }
    if ($email == "") {
        // if the email is blank… give error notice.
        echo "<p>Please enter your e-mail address so that we can reply to you.</p>";
        $submitted = FALSE;  // Set this to FALSE so that it the message is not sent.
    }
    if ($message == "") {
        // if the message is blank… give error notice.
        echo "<p>Please enter a message.</p>";
        $submitted = FALSE;  // Set this to FALSE so that it the message is not sent.
    }
    if ($_POST['email'] != "" && (!strstr($_POST['email'], "@") || !strstr($_POST['email'], "."))) {
        // if the string does not contain "@" OR the string does not contain "." then…
        // supply a different error notice.
        echo "<p>Please enter a valid e-mail address.</p>";
        $submitted = FALSE;  // Set this to FALSE so that it the message is not sent.
    }
    $to = "genxcoders@gmail.com";  // Set the target email address.
    $header = "From: $email";
    $attention = "$name has sent you contact e-mail from GenXCoders.in Contact Form!";
    $message = "Attention: $attention \n From: $name \n Message: $message \n";
    if ($submitted == TRUE) {
        mail($to, $attention, $message, $header);
        echo "<p>Thank you $name. Your message has been sent.</p>";
    }
}
?>

我的 HTML 代码是:

<form id="form" method="post" action="<?php echo $_SERVER['SCRIPT_NAME'] ?>">
    <fieldset>
        <p>
            <label>
                <input name="name" value="Name" onBlur="if (this.value == '')
                            this.value = 'Name'" onFocus="if (this.value == 'Name')
                                        this.value = ''"/>
            </label>

        </p>
        <div class="btns">
            <a href="" class="button">
                Clear
            </a>
            <a href="#" class="button" onClick="document.getElementById('form').submit()">
                Send
            </a>
        </div>  
    </fieldset>
</form>

Answer 1

您可以通过添加另一个类将图像用作 .button 类的 background，或者您可以使用 a 标记包装图像。

例如:HTML

    <a href="#" class="button btn-send" onClick="document.getElementById('form').submit()">
    </a>

CSS

.btn-send {
  width:40px; /* width of the image or button */
  height:20px; /* height of the image or button */
  background-image: url('path-to-image') no-repeat top left;
  }

或

   <a href="#" class="button" onClick="document.getElementById('form').submit()">
     <img src="/path-to-image" alt="Send" />
            </a>
