PHP表格行mi_name与item_name值相等时禁用对应行按钮的实现问题

你只需要在循环输出按钮的位置增加相等判断逻辑，满足条件时给按钮添加disabled禁用属性即可，同时我还修正了你原有代码里按钮type属性拼写错误、表格属性缺引号的小问题。

修改后的完整代码 #

<?php
    require_once('conn.php');

    $sql_count="SELECT COUNT(mi_number)
    FROM a_items z INNER JOIN m3data_items_all a ON (a.mi_number =z.item_number) 
    where plan_id=11 ";
    $Info_count = mysqli_query($con, $sql_count) or die(mysqli_error());
    $row_Info_count = mysqli_fetch_all($Info_count,MYSQLI_ASSOC);


    $sql_row="SELECT mi_number,item_number, mi_name,item_name,mi_description,item_description,plan_id 
                FROM a_items z INNER JOIN m3data_items_all a ON (a.mi_number =z.item_number) 
                where plan_id=11 ";
    $Info_data = mysqli_query($con, $sql_row) or die(mysqli_error());
    $row_Info_data = mysqli_fetch_all($Info_data,MYSQLI_ASSOC);
    
    echo "<div><h2>Count  : ".$row_Info_count[0]['COUNT(mi_number)']."<h2></div><table border='1px' cellpadding='5px' cellspacing='0px'>
    <h1>ALL FETCH  DATA</h1>
    <tr>
    <th>mi_number</th>
    <th>item_number</th>
    <th>mi_name</th>
    <th>item_name</th>
    <th>mi_description</th>
    <th>item_description</th>
    <th>plan_id</th>
    </tr>";

    foreach($row_Info_data as $data){
        // 核心判断：mi_name和item_name相等则给按钮加禁用属性
        $disableAttr = $data['mi_name'] == $data['item_name'] ? 'disabled' : '';
        echo "<tr>
        <td>".$data['mi_number']."</td>
        <td>".$data['item_number']."</td> 
        <td>".$data['mi_name']."</td> 
        <td>".$data['item_name']."</td>
        <td>".$data['mi_description']."</td>
        <td>".$data['item_description']."</td>
        <td>".$data['plan_id']."</td>
        <td><button type='button' {$disableAttr}>Compare me!</button></td>
        </tr>";
    }
    echo "</table>";
?>

核心逻辑说明 #

• 遍历每行数据时通过三目运算符做值比较，两个字段值相等时$disableAttr变量值为disabled，否则为空
• 将变量插入到button标签的属性位置，即可实现符合条件时自动禁用按钮，不需要额外的JS逻辑
