我有一个表，它应该根据同一行中的选择从数据库中检索所有行。
HTML 和 PHP 代码
<div class="row">
<div class="table-responsive">
<table class="table table-bordered" id="tab_logic">
<thead>
<tr>
<th>Brand Name</th>
<th>Item Name</th>
<th>Model Number</th>
<th class="col-md-2">Item Description</th>
<th>Part Number</th>
<th>Unit</th>
<th class="col-md-1">QTY</th>
<th class="col-md-1">Unit Price (SR)</th>
<th class="col-md-1">Total Price (SR)</th>
</tr>
</thead>
<tbody>
<tr>
<td>
<strong>Record</strong>
</td>
<td>
<strong>Record</strong>
</td>
<td>
<strong>Record</strong>
</td>
<td>
<div class="form-group">
<?php
$query = $con->query("SELECT products_itemDescription FROM pruc_products"); // Run your query --> For Item Desc.
echo '<select class="form-control" id="DescriptionS2forms" name="itemDescription">'; // Open your drop down box
echo '<option value="" selected="selected" disabled></option>'; //Empty Value for VALIDATION
// Loop through the query results, outputing the options one by one
while ($row = $query->fetch(PDO::FETCH_ASSOC)) {
echo '<option value="'.$row['products_itemDescription'].'">'.$row['products_itemDescription'].'</option>';
}
echo '</select>';// Close your drop down box
?>
</div>
</td>
<td>
<strong>Record</strong>
</td>
<td>
<strong>Record</strong>
</td>
<td>
<div>
<input class="form-control" type="number" name="requestQTY" required>
</div>
</td>
<td>
<div>
<input class="form-control" type="number" name="requestUnit" step="0.01" min="0.01" max="1000000" required>
</div>
</td>
<td>
<strong>Record</strong>
</td>
<td class="col-md-1" id="deleteBtn">
<a class="btn btn-default deleteBtn">Delete</a>
</td>
</tr>
</tbody>
</table>
</div>
</div>
因此，我定义了此选择，它是从数据库中获取的，因此我还需要获取每个“记录”，但基于我将从选择选项卡中进行的选择。
PHP 和 SQL 查询
<?php
$sql = $con->prepare("SELECT products_brandName FROM pruc_products WHERE products_brandName, products_itemDescription = (products_id)") ;
$sql->execute() ;
while( $row = $sql->fetch()):
echo '<strong>'.$row['products_brandName'].'</strong>';
endwhile ?>
对此有什么帮助吗？
最佳答案
products_barndName 需要等于某些内容。另外，不要使用逗号来分隔 WHERE 子句中的条件。试试这个:
WHERE products_brandName = 'x' AND products_itemDescription = (products_id)
