Question

示例MySQL查询：返回的是两个值（Desert和Grasslands。）我想将这两个值与checkboxes匹配为"checked"其他值将保留unchecked。

我的PHP结果集：

$row[biome];

<?php
while($row = mysqli_fetch_assoc($selectQueryBiomeResult)) {
     echo '<input type="checkbox" name="biomeCheck[]" value="Desert"> Desert';
     echo '<input type="checkbox" name="biomeCheck[]" value="Grasslands"> Grasslands';
     echo '<input type="checkbox" name="biomeCheck[]" value="Deciduous Forest"> Deciduous Forest';
     echo '<input type="checkbox" name="biomeCheck[]" value="Tropical Rainforest"> Tropical Rainforest';
}
?>

Answer 1

提供示例代码 -

<html>

    <?php
        mysql_connect("host", "username", "pwd") or die("connect error");
        mysql_select_db("db_name");
        $res=mysql_query("write your query here");
        $val_array=array();
        while($row=mysql_fetch_array($res))
        {
            $val_array[]=$row[0];
        }
    ?>

    <body>
        <input type="checkbox" name="biomeCheck[]" value="Desert" <?php if(in_array("Desert", $val_array)) echo "checked"?>> Desert;
        <input type="checkbox" name="biomeCheck[]" value="Grasslands" <?php if(in_array("Grasslands", $val_array)) echo "checked"?>> Grasslands;
        <input type="checkbox" name="biomeCheck[]" value="Deciduous Forest" <?php if(in_array("Deciduous Forest", $val_array)) echo "checked"?>> Deciduous Forest;
        <input type="checkbox" name="biomeCheck[]" value="Tropical Rainforest" <?php if(in_array("Tropical Rainforest", $val_array)) echo "checked"?>> Tropical Rainforest;
    </body>

</html>

Answer 2

如果你的结果是数组，那么试试这个

示例数组

$my_array = array(
    'first' => 'Desert', 
    'second' => 'Grasslands', 
    'third' => 'Deciduous Forest'
);

<input type="checkbox" name="vehicle" value="Desert" <?php if(in_array('Desert', $my_array)) echo( 'checked = "checked"'); ?>/> Desert<br />

PHP / MySQL标记多个复选框“已选中”或未根据返回的数据进行检查
