Smarty can encode URLs directly, such as
But in the smarttemplate as if there is no, because the link is submitted by JS, not the form submission, so it cannot be automatically encoded.
Workaround: Use JS to the URL of the Chinese character escape code.
When you click the link, the effect is:
Reference: http://127.0.0.1/shop/product_list.php?p_sort=PHP%u5F00%u53D1%u8D44%u6E90%u7F51
The result is that the UrlDecode () or Base64_decode () in PHP is clearly not solvable.
Workaround, write an inverse function in PHP:
Copy CodeThe code is as follows:
function Js_unescape ($STR)
{
$ret = ";
$len = strlen ($STR);
for ($i = 0; $i < $len; $i + +)
{
if ($str [$i] = = '% ' && $str [$i +1] = = ' U ')
{
$val = Hexdec (substr ($str, $i +2, 4));
if ($val < 0x7f) $ret. = Chr ($val);
else if ($val < 0x800) $ret. = Chr (0xc0| ( $val >>6). Chr (0x80| ( $val &0x3f));
else $ret. = Chr (0xe0| ( $val >>12). Chr (0x80| ( ($val >>6) &0x3f). Chr (0x80| ( $val &0x3f));
$i + = 5;
}
else if ($str [$i] = = '% ')
{
$ret. = UrlDecode (substr ($str, $i, 3));
$i + = 2;
}
else $ret. = $str [$i];
}
return $ret;
}
Note that the JS encoding will automatically be converted into UTF-8, so the encoding must be converted to get the correct results, otherwise it will be garbled in Chinese.
The code is as follows:
Print iconv (' utf-8 ', ' gb2312 ', Js_unescape ($_request[' p_sort '));
To this we have successfully reversed the JS escape code.
As follows:

In addition, I found a PHP implementation of the Escape encoding function:
Copy CodeThe code is as follows:
function Phpescape ($STR)
{
$sublen =strlen ($STR);
$retrunString = "";
for ($i =0; $i < $sublen; $i + +)
{
if (Ord ($str [$i]) >=127)
{
$tmpString =bin2hex (Iconv ("gb2312", "Ucs-2", substr ($str, $i, 2)));
$tmpString =substr ($tmpString, 2,2). substr ($tmpString, 0,2); window may open this
$retrunString. = "%u". $tmpString;
$i + +;
} else {
$retrunString. = "%". Dechex (Ord ($str [$i]);
}
}
return $retrunString;
}
Have you ever encountered such a problem?
