我用来执行此请求的所有代码,您有什么想法吗? 谢谢。
注意:当我在我的模型功能中给出一个值时,它会起作用。
jobs.description =%s -with-&gt; jobs.description =&#34;价值&#34;
答案 0 :(得分:0)
thas是我在models.py中的解决方案,它可以工作:)
if ($hasVoted < 1) {
echo "<div class='upvoteDownvoteRatingContainer'><form class='upvoteImage' method='POST' action=''>
<input type='hidden' name='action' value='upvote'>
<input type='hidden' name='id' value='".$row['id']."'>
<input type='hidden' name='userId' value='".$currentUser."'>
<button class='upvoteImageButton' type='submit' name='upvoteImage'><img class='arrowUp' src='../images/Social Media/arrowUp.png' alt='submit'></button>
</form>";
</div>
