return ' ';里怎么插入函数?
如下,我想在a href里插入函数the_permalink()
if(a>b){
return '
}
试过用echo输出,虽然能插入the_permalink(),但图片会居所有文字之上,return输出的图片则会在预设的位置,不知怎么解决

不明白你说的意思
不明白你说的意思
意思是让这句话没有语法错误,让the_permalink()的值能输出
return '
显然是位置不对。。。
你这样写不就是对的吗?
当然 the_permalink 中也是 return 的
你这样写不就是对的吗?
当然 the_permalink 中也是 return 的
这样输出结果有问题,href得到的值是空的,the_permalink()的值却直接显示出来
1、the_permalink() 返回的是什么?
2、你这样写后得到的是什么?
3、你期望得到的是什么?
1、the_permalink() 返回的是什么?
2、你这样写后得到的是什么?
3、你期望得到的是什么?
1.the_permalink()返回http://xxxx.com/123.html
2.图片没有链接,图片上面显示http://xxxx.com/123.html
3.给图片加链接http://xxxx.com/123.html
我猜测: 你the_permalink()最终没有 return “http://xxxx.com/123.html” 而是echo “http://xxxx.com/123.html”
