如何在MySQL中一次存儲多個單選按鈕？

Question

這是我的PHP腳本，它爲每一行列出了所有我的標記（來自MySQL數據庫），並帶有兩個單選按鈕（啓用和禁用）。我如何將更改（如果啓用或禁用某些內容）保存到MySQL數據庫中？無論我啓用還是禁用圖書，都應該保存值1或2.

<?php 
$result = mysqli_query($mysqli,"SELECT * FROM tags ORDER BY id ASC"); 
while($row = mysqli_fetch_array($result)) { 
if($row['enabled'] == 1) { 
echo '<input type="radio" name="' . $row['id'] . '" value="1" checked>Enable' . 
    '<input type="radio" name="' . $row['id'] . '" value="2">Disable '; 
} else { 
echo '<input type="radio" name="' . $row['id'] . '" value="1">Enable' . 
    '<input type="radio" name="' . $row['id'] . '" value="2" checked>Disable '; 
} 
echo $row['tagname'] . "<br />"; 
} 
?> 

謝謝。我希望你明白我的問題！ :-)

我會解釋引述/* */我的代碼，因爲我走的更遠：

<?php 

/* ESTABLISH YOUR CONNECTION */ 

$mysqli=mysqli_connect("Host","Username","Password","Database"); /* JUST REPLACE THE NECESSARY HOST, USERNAME, PASSWORD AND DATABASE */ 

if(mysqli_connect_errno()){ 

echo "Error".mysqli_connect_error(); 
} 

if(isset($_POST['submit'])){ /* IF FORM HAS BEEN SUBMITTED */ 

/* STORE THE SUBMITTED POST DATA */ 

$counter=$_POST['hiddencounter']; 
$radio=$_POST['radio']; 
$id=$_POST['id']; 

for($x=0;$x<=$counter;$x++){ /* FOR LOOP BASED ON THE HIDDEN COUNTER */ 

mysqli_query($mysqli,"UPDATE tags SET enabled='$radio[$x]' WHERE id='$id[$x]'"); /* UPDATE THE enabled COLUMN WITH THE CORRESPONDING SUBMITTED RADION BUTTON */ 

} /* END OF FOR LOOP */ 

} /* END OF ISSET */ 

$result = mysqli_query($mysqli,"SELECT * FROM tags ORDER BY id ASC"); 

echo "<form action='' method='POST'>"; /* SUBMIT ON PAGE ITSELF */ 

$counter=0; /* WILL SET AS YOUR COUNTER FOR ARRAY PURPOSES */ 

while($row = mysqli_fetch_array($result)) { 

if($row['enabled'] == 1) { 
echo "<input type='radio' name='radio[$counter]' value='1' checked> Enable <input type='radio' name='radio[$counter]' value='2'> Disable "; /* STORE THE RADIO BUTTON'S VALUE IN AN ARRAY */ 
} 

else { 
echo "<input type='radio' name='radio[$counter]' value='1'> Enable <input type='radio' name='radio[$counter]' value='2' checked> Disable "; /* STORE THE RADIO BUTTON'S VALUE IN AN ARRAY */ 
} 

echo "<input type='hidden' name='id[$counter]' value='$row[id]'>"; /* STORE THE ID IN AN ARRAY */ 

$counter=$counter+1; 
echo $row['tagname'] . "<br />"; 
} /* END OF WHILE LOOP */ 

echo "<input type='hidden' name='hiddencounter' value='$counter'>"; /* STORE THE TOTAL COUNT IN THE LOOP */ 
echo "<input type='submit' name='submit' value='Update'>"; 
echo "</form>"; 

?>

你不應該保存單選按鈕，而是保存狀態。如果可以啓用或禁用狀態（或：啓用，是或否），則可以將其存儲在名爲'enabled'的字段中，該字段爲布爾類型，即在MySQL中爲BOOL。

如果您想保留其他國家的可能性，可以將其存儲在名爲'state'的字段中，該字段的類型爲INT或ENUM。

BOOL：https://dev.mysql.com/doc/refman/5.0/en/numeric-type-overview.html（它是TINYINT的別名（1）

ENUM：https://dev.mysql.com/doc/refman/5.0/en/enum.html
