Question

我在Blade视图中创建了此函数，该函数从API返回数据。如何将这些数据作为值传递给HTML输入字段？

我的内联php代码：

@php
    function getPrice()
    {
        $url = "https://bitpay.com/api/rates";
        $json = json_decode(file_get_contents($url));
        foreach($json as $obj)
        {
            if($obj->code == 'USD')
            $btc = $obj->rate;
        }
        echo $btc;
    }
@endphp

我要将上述数据传递到的HTML输入字段：

 <p class="form-group"> 
    <label for="subject">Amount in BTC<span class="required">*</span></label>
    <i class="fa fa-btc "></i> 
  <input type="text" aria-required="true" size="30" value="" name="btc" id="btc" class="form-control" placeholder="Amount in Bitcoin" readonly="true" >
</p>

Answer 1

确定要使用function()吗？您可以直接离开：

@php
    $btc = null; (?)
    $url = "https://bitpay.com/api/rates";
    $json = json_decode(file_get_contents($url));
    foreach($json as $obj)
    {
        if($obj->code == 'USD')
            $btc = $obj->rate;
    }
@endphp

及之后：

<input type="text" aria-required="true" size="30" value="{{ $btc }}" name="btc" id="btc" class="form-control" placeholder="Amount in Bitcoin" readonly="true" >

我已经更新了这篇文章。您无需创建函数。都不回显该变量。就是这样：

<?php              
    $url = "https://bitpay.com/api/rates";
    $json = json_decode(file_get_contents($url));
    foreach($json as $obj){
        if($obj->code == 'USD')
        {
            $btc = $obj->rate;
        }
    }
?>

并假定两个代码都在同一刀片文件中。您只需像这样调用变量：

 <input type="text" aria-required="true" size="30" value="" name="btc" id="btc" class="form-control" placeholder="Amount in Bitcoin" readonly="true" value = "{{$btc}}" >
