我正在使用PHP做考试系统。我正在尝试向图像添加问题,并将图像移到指定的文件夹中以进行检索。我有以下代码:
$sql = 'SELECT q_category, q_image, q_question, q_correct, q_answer2, q_answer3, q_answer4 FROM tblquestions WHERE q_question = "' . $question . '"';
$retval = mysql_query($sql,$conn);
if(!$retval)
{
die('Could not get data: ' . mysql_error());
}
while($row1 = mysql_fetch_array($retval, MYSQL_ASSOC))
{
$cat = $row1['q_category'];
$quest = $row1['q_question'];
$image = $row1['q_image'];
$correct = $row1['q_correct'];
$ans2 = $row1['q_answer2'];
$ans3 = $row1['q_answer3'];
$ans4 = $row1['q_answer4'];
echo '<tr>';
echo '<td colspan="2"><div class="selectText" align="center">Edit Questions</div></td></tr>';
echo '<tr>';
echo '<td>Category</td>';
echo '<td><input type="text" name="txtCategory" value = "' . $cat . '" size="38"></td>';
echo '</tr>';
echo '<tr>';
echo '<td>Question</td>';
echo '<td><textarea rows="4" cols="34" name="txtQuestion" id="txtQuestion" class="addNew">' . $quest . '</textarea>';
echo '</tr>';
echo '<tr>';
echo '<td>Image</td>';
echo '<td><input type="file" rows="4" cols="28" name="txtImage" id="txtImage" class="addNew"></td>';
echo '</tr>';
echo '<tr>';
echo '<td>Correct Answer</td>';
echo '<td><input type="text" name="txtCorrect" value = "' . $correct . '" size="38"></td>';
echo '</tr>';
echo '<tr>';
echo '<td>Answer 2</td>';
echo '<td><input type="text" name="txtChoice2" value = "' . $ans2 . '" size="38"></td>';
echo '</tr>';
echo '<tr>';
echo '<td>Answer 3</td>';
echo '<td><input type="text" name="txtChoice3" value = "' . $ans3 . '" size="38"></td>';
echo '</tr>';
echo '<tr>';
echo '<td>Answer 4</td>';
echo '<td><input type="text" name="txtChoice4" value = "' . $ans4 . '" size="38"></td>';
echo '</tr>';
echo '<input type="hidden" name="hiddenQuestion" value = "' . $question . '">';
}
if(isset($_POST['submit1']))
{
$hiddenQuestion = $_POST['hiddenQuestion'];
$addCategory = $_POST['txtCategory'];
$addQuestion = $_POST['txtQuestion'];
$addCorrect = $_POST['txtCorrect'];
$addChoice2 = $_POST['txtChoice2'];
$addChoice3 = $_POST['txtChoice3'];
$addChoice4 = $_POST['txtChoice4'];
$filetmp = $_FILES['txtImage']['tmp_name'];
$filename = $_FILES['txtImage']['name'];
$filepath = "questionImages/".$filename;
move_uploaded_file($filetmp,$filepath);
单击提交后,$ filename在数据库中为空,并且move_uploaded_file不起作用。如果我将$ filename = $ _FILES ['txtImage'] ['name']更改为$ filename = $ _POST ['txtImage'],它将名称添加到数据库中,但是move_uploaded文件仍然不起作用。
问题我在想我的$ filetmp和$ filename出了点问题。谁能指出我的代码出了什么问题?提前致谢 :)
$filename
而$filetype
似乎确定。
在您的上传表单中检查是否包含enctype="multipart/form-data"
。
在问题中还包括您的表单代码。
