有特殊字符

Question

我有一個WordPress頁面

$str = 's.aspx?sm=Q830I7SJZvuSP3HzDfFlVA%3d%3d'; 

printf('<a href="https://www.surveymonkey.com/.urlencode($str)." target="_blank"> 
      <img src="http://www.anyfood.gr/net/wp-content/uploads/2014/12/evaluation2.jpg" style="padding:20px;"> 
     </a>' 
); 

但鏈接不起作用此PHP代碼的PHP腳本的URL，我已經用單引號試了幾個可能的招數，等等 但我可以想不出來...有什麼想法？

Answer 1

當訪問GET參數時，通常不需要使用urldecode()。使用它作爲如下：

$str = 's.aspx?sm=' . urlencode ('Q830I7SJZvuSP3HzDfFlVA%3d%3d'); 

echo '<a href="https://www.surveymonkey.com/'.$str.'" target="_blank"> 
     <img src="http://www.anyfood.gr/net/wp-content/uploads/2014/12/evaluation2.jpg" style="padding:20px;"> 
    </a>'; 

Answer 2

$str = 's.aspx?sm=Q830I7SJZvuSP3HzDfFlVA%3d%3d'; 

printf(' 
*<*a href="https://www.surveymonkey.com/".urlencode($str) target="_blank"> 
    *<*img src="http://www.anyfood.gr/net/wp-content/uploads/2014/12/evaluation2.jpg" style="padding:20px;"> 
    </a> 
'); 

**刪除*在錨標記和圖像標記**

Answer 3

的出發試試這個，它的工作對我來說：

<?php 
$str = 's.aspx?sm=Q830I7SJZvuSP3HzDfFlVA%3d%3d'; 

printf('<a href="https://www.surveymonkey.com/%1$s " target="_blank"> <img src="http://www.anyfood.gr/net/wp-content/uploads/2014/12/evaluation2.jpg" style="padding:20px;"> </a>', urlencode($str)); 
?> 

Answer 4

$str = 's.aspx?sm=Q830I7SJZvuSP3HzDfFlVA%3d%3d'; 

printf('< a href="https://www.surveymonkey.com/%s" target="_blank"> 
      <img src="http://www.anyfood.gr/net/wp-content/uploads/2014/12/evaluation2.jpg" style="padding:20px;"> 
     </ a>', urlencode($str)); 

檢查此。
