语法错误，意外的"if"(T_IF) [英] syntax error, unexpected 'if' (T_IF)

问题描述

我想我一直盯着这个问题已经太久了，以至于现在我无法发现问题所在.

I think I've been staring at this for too long that now I'm failing to identify the problem.

有人可以指出这是哪里出了问题吗?

Can someone kindly point out where this is going wrong?

错误:

Parse error: syntax error, unexpected 'if' (T_IF) in /Applications/MAMP/htdocs/mipbi/includes/classes/html.php on line 11

代码:

public static function textbox($name, $maxlength=''){
    return "<input type='text' id='$name' name='$name'  maxlength='$maxlength' value='". if (isset($_POST[$name])) { echo $name; } ."' >";
}

在if语句行生成错误.

The error is generated at the if statement line.

推荐答案

您不能使用if语句.

要完成您想实现的目标，您需要这样做:

To do what you want to achieve you'll need to do this:

public static function textbox($name, $maxlength=''){
    return "<input type='text' id='$name' name='$name'  maxlength='$maxlength' value='".(isset($_POST[$name]) ? $name : '')."' >";
}
