我将使用表单将嵌入的视频代码输入到表单字段中,以便将其存储到MYSQL数据库中。 iframe滚动,宽度,高度,框架边框和src不应存储在数据库中。如何使用php preg_match函数从嵌入的视频代码中删除iframe滚动,宽度,高度,框架边框和src。我只想要URL id到视频。如何仅存储嵌入视频的链接而不是其所有属性? 这是代码:
<?php
$servername = "localhost";
$username = "root";
$password = "";
// Create connection
$conn = mysqli_connect($servername, $username, $password);
// Check connection
if (!$conn) {
die("Connection failed: " . mysqli_connect_error());
}
if(!mysqli_select_db($conn,'tutorial'))
{
echo 'Database not selected';
}
$title = test_input($_POST['title']);
$embedded_video = test_input($_POST['embedded_video']);
//I want preg_match to remove, src, iframe scrolling, width, height, and frameborder out of embeded code
if (preg_match(%^(src)"/\b(?:(?:https?|ftp):\/\/|www\.)[-a-z0-9+&@#\/%?=~_|!:,.;]*[-a-z0-9+&@#\/%=~_|]/i",$embedded_video)) {
//puting the URL of video in database
$sql = "INSERT INTO person(title,embedded_video) VALUES ('$title', '$embedded_video')";
}
}
if(!mysqli_query($conn, $sql))
{
echo "Not inserted";
}
else {
echo "INSERT";
}
function test_input($data) {
$data = trim($data);
$data = stripslashes($data);
$data = htmlspecialchars($data);
return $data;
}
?>
<!DOCTYPE html>
<html>
<body>
<form method="post" action="<?php echo htmlspecialchars($_SERVER["PHP_SELF"]);?>">
<input type="text" name="title" >
<br>
Embedded video:<br>
<input type="text" name="embedded_video">
<br><br>
<input type="submit" value="Insert">
</form>
</body>
</html>

您可以为preg_match()
第三个变量array()
。这将匹配存储在第一个索引上,任何部分匹配其他索引。
我认为这将是您的解决方案:
if (preg_match(%^(src)"/\b(?:(?:https?|ftp):\/\/|www\.)[-a-z0-9+&@#\/%?=~_|!:,.;]*[-a-z0-9+&@#\/%=~_|]/i", $embedded_video, $matches)) {
//puting the URL of video in database
$sql = "INSERT INTO person(title,embedded_video) VALUES ('" . $title . "', '" . $matches[0] . "')";
}
(在}
之后你使用了if statement
太多了!)
