[英]get_permalink for json_decode not working
This is probably a straight forward fix, but I really can't get it to work. 这可能是一个简单的解决方法,但我真的无法使其正常工作。 My code reads as follows: 我的代码如下:
PHP (functions.php) PHP (functions.php)
<?php
class shareCount {
private $url,$timeout;
function __construct($url,$timeout=10) {
$this->url=rawurlencode($url);
$this->timeout=$timeout;
}
function get_tweets() {
$json_string = $this->file_get_contents_curl(
'http://urls.api.twitter.com/1/urls/count.json?url=' . $this->url
);
$json = json_decode($json_string, true);
return isset($json['count'])?intval($json['count']):0;
}
}
?>
As you can see there are two functions above: one which gets the link to be decoded and another to decode the json information and return a digit. 如您所见,上面有两个函数:一个用于获取要解码的链接,另一个用于对json信息进行解码并返回一个数字。
I call the two functions in my html as follows: 我在html中调用这两个函数,如下所示:
<div>
<?php
$obj=new shareCount("get_permalink()");
echo $obj->get_tweets();
?>
</div>
The issue I have is that in the html/php, where i call the functions, "get_permalink"
will not work inside the the ""
marks. 我的问题是在html / php中,我在其中调用函数的地方, "get_permalink"
在""
标记内不起作用。 If i remove the quotation marks it also doesn't work. 如果我删除引号,它也不起作用。 The only way this setup seems to work is if a link is manually placed inside the quotes. 此设置似乎起作用的唯一方法是在引号内手动放置一个链接。
I need to use get_permalink()
or something similar to pull the current post url and then add the json_decode
function to it. 我需要使用get_permalink()
或类似的方法来提取当前的发布网址,然后向其添加json_decode
函数。
Thanks 谢谢
For anyone with the same issue , I have found the solution to this problem. 对于有相同问题的任何人,我都找到了解决此问题的方法。 It took a while but i finally fixed it. 花了一段时间,但我终于解决了。 The final code is as follows: 最终代码如下:
PHP (functions.php) PHP(functions.php)
<?php
function get_tweets($url) {
$url = get_permalink($post->ID)
$json_string = $this->file_get_contents_curl(
'http://urls.api.twitter.com/1/urls/count.json?url=' . $url
);
$json = json_decode($json_string, true);
return isset($json['count'])?intval($json['count']):0;
}
}
?>
And call the function in HTML as follows: 并按以下方式在HTML中调用该函数:
<div>
<?php
echo get_tweets($url);
?>
</div>
Basically you need to specify that the php function "get_tweets" is a url. 基本上,您需要指定php函数“ get_tweets”是一个url。 Then specifiy that url as "$url = get_permalink($post->ID). Then when you call the function in html just write echo get_tweets ($url). 然后,将该URL指定为“ $ url = get_permalink($ post-> ID)。然后,当您在html中调用该函数时,只需编写echo get_tweets($ url)。
$ this-> file_get_contents_curl替换为file_get_contents
