[英]how to set max value in quantity update in codeigniter cart
<?php echo form_input('cart[' . $item['id'] . '][qty]', $item['qty'], max=> $item['price'] ' type="number" min="1" value="1" )'; ?>
如何设置最大值它显示我语法错误,意外的“=>”(T_DOUBLE_ARROW)
Easiest way is to pass associative array,最简单的方法是传递关联数组,
<?php
echo form_input(
array(
'name'=> 'cart[' . $item['id'] . '][qty]',
'type'=>"number",
'min'=>1,
'max'=> $item['price'],
'value'=> $item['qty'],
)
);
?>
You still can correct your existing one like below您仍然可以像下面这样更正现有的
<?php
echo form_input(
/*name*/
'cart[' . $item['id'] . '][qty]',
/* value */
$item['qty'],
/* other attributes as string */
'max="'.$item['price'].'" type="number" min="1"'
);
?>
