Question

我一直在寻找我的问题的答案，但我找不到一个，

我正在从db输入数据中检索数据，并再次将输入字段中更改的值更新为db。

这是我的代码

echo "<table>";
while ($row = mysql_fetch_array($result)){
echo "<form method=\"GET\"  action=\" ".htmlspecialchars($_SERVER['PHP_SELF'])."\" > ";
echo "<tr><td>ID:</td><td>Company Name</td><td>Date for Service</td><td>Edit</td><td>Delete</td></tr>";
echo "<td><input type= 'text' name = 'jobrequestnumber' value =".$row['jobrequestnumber']."></td>"  ; // results in the same jobrequestnumbers
echo "<td><input type= 'text' name = 'requestingcompany' value =".$row['requestingcompany']."></td>"    ;//this too
echo "<td><input type= 'date' name = 'dateforService' value =".$row['dateforService']."></td>"  ;// this one also 
echo "<td><a href='delete.php?jobrequestnumber=".$row['jobrequestnumber']."'>Delete</a></td>"; //too
echo "</form> ";
echo "<td><a href=\"update_request.php?jobrequestnumber='jobrequestnumber'&requestingcompany='requestingcompany'&dateforService='dateforService'\">Update</a></td>";
echo "</tr>";
}
echo "</table>";

在一个链接中，我试图通过引用输入字段的名称来传递值，但它不起作用。！

还有其他方法或有人可以解决这个问题吗？

非常感谢。

Answer 1

使用post而不是get

echo "<table>";
echo "<tr><td>ID:</td><td>Company Name</td><td>Date for Service</td><td>Edit</td><td>Delete</td></tr>";

while ($row = mysql_fetch_array($result)){
echo "<form method=\"post\"  action=\" ".htmlspecialchars($_SERVER['PHP_SELF'])."\" > 
<input name=\"id\" type=\"hidden\" value=\"".$row['jobrequestnumber']."\">
"; // added hidden id for update


echo "<td><input type= 'text' name = 'jobrequestnumber' value =".$row['jobrequestnumber']."></td>"  ; // results in the same jobrequestnumbers
echo "<td><input type= 'text' name = 'requestingcompany' value =".$row['requestingcompany']."></td>"    ;//this too
echo "<td><input type= 'date' name = 'dateforService' value =".$row['dateforService']."></td>"  ;// this one also 
echo "<td><a href='delete.php?jobrequestnumber=".$row['jobrequestnumber']."'>Delete</a></td>"; //too
echo " ";
echo "<td><input name=\"update\" type=\"submit\" value=\"update\"></td>";
echo "</tr></form>";
}
echo "</table>";

你需要使用mysql_fetch_assoc（）而不是mysql_fetch_array
