接收PHP变量

Question

接收变量时遇到问题,我收到的错误消息是

注意:未定义的索引:第7行的C:\ Users\PC\Documents\XAMPP\htdocs\php\addpost.php中的标题注意:未定义的索引:C:\ Users\PC\Documents\XAMPP\htdocs\php \中的文本第8行的addpost.php

// HTML文档

<div id="postdialog" title="Add Post" action="php/addpost.php">
<p>Please Fill in out member information.</p>
<form name="insertmember" action="php/addpost.php" >
<label>Title<input type="text" name="title" id="title"/></label>
<label>Text<textarea name="text"></textarea></label>
<input name="submit" type="submit" value="Submit" id="submit" />  
</form>
</div>

// PHP文件

if ($_POST['submit'] = "submit") {

    $title = $_POST['title']; 
    $text  = $_POST['text']; 

    $errors = array();

    if (empty($_POST['title'])) {
        $errors[] = "Title is Missing";
}
else 
{
    $title = $_POST['title'] 
    if (strlen($fname) > 15 ) {
        $errors[] = "Title is too long";
    }
}

if (empty($_POST["text"])) {
    $errors[] = "Text is Missing";
}   
else 
{
    $text = $_POST['text'] 
    if (strlen($lname) > 30 ) {
        $errors[] = "Text is too long";
    }
}

if (!empty($errors)) {
    print_r ($errors);
}
else 
{
    //DO SOMETHING ELSE
}

您没有method在表单中指定,因此默认为GET.

您需要添加method="post"到表单标记或搜索您的数据$_GET.
