Question

输入名称为“ option [] [width]”，因为我要2个输入乘法，但不会崩溃。请输入这样的名称。

<?php 
    $height = null; 
    $width = null; 
    function vir2nok($data) { 
        return str_replace(",",".",$data); 
    } 
    if ($_POST) { 
        $height = vir2nok($_POST["height"]); 
        $width = vir2nok($_POST["width"]); 
        if (is_numeric($height) && is_numeric($width)) { 
            $sonuc = $height * $width; 
            echo $height." x ".$width." = ".$sonuc."<hr>"; 
        } 
    } 
?> 


<form action="" method="post"> 

<input type="text" name="option[<?php echo $option['product_option_id']; ?>][height]"  placeholder="<?php echo $label_height; ?>" id="input-option<?php echo $option['product_option_id']; ?>" class="pso-height-input form-control" />
<input type="text" name="option[<?php echo $option['product_option_id']; ?>][width]"  placeholder="<?php echo $label_width; ?>" id="input-option<?php echo $option['product_option_id']; ?>" class="pso-width-input form-control" />

 <input type="submit" name="gonder"> 
</form>

您没有正确访问字段，请尝试将这两行更改为：

router.get('/', (req, res) => {
  Intro.find({}, (err, items) => {
    if (err) {
      res.send("Something went wrong: " + err);
    } else {
      res.render('index', {
        title: items[0].title
      })
    }
  });
});

两个数组乘法名称x
