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";
}
} …我想查询数据库并从多行中提取检索信息,但我不确定MySQL语法.像这样的东西;
SELECT LastName FROM Users WHERE ID = 1 AND ID = 2 AND ID = 3
所以我想收回来
Smith,Doe和Doe
Users
ID FirstName LastName
1 John Smith
2 Joe Doe
3 Jane Doe
More data etc etc
