在该代码中，即使值已更改而非($content = 'europe')更改为($content = 'asia')，也只会执行第一个条件。剩余的条件不起作用。
function test(){
if($content = 'europe'){
$multi_tlds = $titan->getOption('wdc_europe');
} elseif($content = 'asia'){
$multi_tlds = $titan->getOption('wdc_asia');
} elseif($content = 'africa'){

这是声明变量
$content = 'europe'
应为==
$content='asia';
function test(){
if($content == 'europe'){
$multi_tlds = $titan->getOption('wdc_europe');
} elseif($content == 'asia'){
$multi_tlds = $titan->getOption('wdc_asia');
} elseif($content == 'africa'){
$multi_tlds = $titan->getOption('wdc_africa');
}
}
<input type='radio' name='asia' value='asia'> Asia<br>
<input type='radio' name='europe' value='europe'> Europe<br>
</fieldset>
</div>
<div class='col-sm-3'>
<fieldset>
<input type='radio' name='africa' value='africa'> Africa<br>
这段代码错了，它们应该都有相同的名称
name='myregionchoice'
然后你将它作为帖子处理
$regionchoice=$_POST['item_id'];
然后在if语句中
if($mygreionchoice == 'europe'){
$multi_tlds = $titan->getOption('wdc_europe');
} elseif($myregionchoice == 'asia'){
$multi_tlds = $titan->getOption('wdc_asia');
} elseif($myregionchoice == 'africa'){
$multi_tlds = $titan->getOption('wdc_africa');
}
}

答案 1 :(得分：0)
==用于比较，=将变量与值等同。你需要比较内部而不是等同。
答案 2 :(得分：0)
$content = 'europe'是一个赋值语句，它总是返回true，因此代码始终执行该条件。
我认为你所寻找的是一个比较陈述，它可能是$content == 'europe'（和所有其他值相同）。
此外，您应该将$content变量传递给您的函数，否则未定义：
function test($content) {...}
