我的数据库表

非常感谢您的帮助。我需要 php 代码或 Laravel。

Answer 1

在您的控制器中，您可以将对象传递给刀片模板：

$products = Product::get();
return view('your.blade.view')->with([
    'products' => $products
});

然后在你的刀片模板文件中你可以使用它们：

<select multiple name="property">
    @foreach($products as $product)
        <option value="{{ $product->id }}"> {{ $product->name }} </option>
    @endforeach
</select>

这是一个示例，您需要调整此代码以满足您的需求，但它应该是正确的做法

这个 php 代码可能会有所帮助

<?php
//connect to your database here
require_once("../core/init.php");

//query database
$q_property = $db->query(("select properties from products2"));
$q_animal = $db->query(("select animal_id from products2"));
$q_form = $db->query(("select form from products2"));
?>
<div class="row pad_y_20">
  <div class="col s12">
            <h3 class="c_black center-align bold">Search for Our 
Products</h3>
    </div>
    <div class="input-field my_arrow col s12 m10 push-m1 l3" >
        <select multiple name="property">
      <option value="" disabled selected>Properties</option>
      <?php
      //we  loop over each property value and echo it to our select input
      while($row = mysqli_fetch_row($q_property)){

        $property = $row[0];
       ?>
      <option value="<?= $property ?>"><?= $property ?></option>
    <?php } ?>
    </select>
    </div>
    <div class="input-field my_arrow col s12 m10 push-m1 l3">
        <select multiple name="target_animal">
      <option value="" disabled selected>Target animals</option>
      <?php
        //we  loop over each animal_id value and echo it to our select input
      while($row = mysqli_fetch_row($q_animal)){

        $animal = $row[0];
       ?>
      <option value="<?= $animal ?>"><?= $animal ?></option>
    <?php } ?>
    </select>
    </div>
    <div class="input-field my_arrow col s12 m10 push-m1 l3">
        <select multiple name="form">
      <option value="" disabled selected>Form</option>
      <?php
        //we  loop over each form value and echo it to our select input
      while($row = mysqli_fetch_row($q_form)){
        $form = $row[0];
       ?>
      <option value="<?= $form ?>"><?= $form ?></option>
    <?php } ?>
    </select>
    </div>
    <div class="col s12 m10 push-m1 l3">
        <input type="submit" value="search"/a>
