Question

我有phpmydatagrid，其中有单独的按钮可供用户输入，删除和编辑数据。有一列用于输入网址，我想验证它（例如：我希望所有用户输入完整的URL与http或https请求，它不应该只是www.something.com），我想知道究竟输入语法的位置我附上了phpmydatagrid的编码。

phpMyDatagrid - 示例文件

/* Include class file */
include ("phpmydatagrid.class.php");

/* Create object */
$objGrid = new datagrid;

/* Define the "FORM" will be named employee and Must be 
   created by the grid script */
$objGrid -> form('employee', true);

/* Connect with the database */
$objGrid -> conectadb("localhost", "root", "mysql", "probe_config");

/* Select the table to use */
$objGrid -> tabla ("measurementurl");

$objGrid -> buttons(addbtn,updbtn,delbtn,false);




$objGrid -> datarows(5);

$objGrid -> paginationmode('mixed');


/* Define fields to show */

  $objGrid -> FormatColumn("id", "ID", 30, 30, 0, "150", "left");
$objGrid -> FormatColumn("name", "NAME", 30, 30, 0, "50", "right");
$objGrid -> FormatColumn("url", "url", 90, 90, 0, "90", "left");
    $objGrid -> FormatColumn("comment", "COMMENT", 30, 30, 0, "150", "left");


$objGrid -> keyfield("id");

   to correctly set the CSS and JS parameters */
$objGrid -> setHeader();

Answer 1

PHP代码：

function isValidURL($url)
{
return preg_match('|^http(s)?://[a-z0-9-]+(.[a-z0-9-]+)*(:[0-9]+)?(/.*)?$|i', $url);
}

使用功能：

PHP代码：

if(!isValidURL($fldbanner_url))
{
$errMsg .= "* Please enter valid URL including http://<br>";
}

Answer 2

如果您安装了过滤器扩展程序，请使用filter_var功能：

if(filter_var($url, FILTER_VALIDATE_URL)) {
  //Valid URL
} else {
  //Invalid URL
}

在php中验证url
