我的两个页面上出现此错误,我无法理解原因。我已经重写了代码并对其进行了三重检查,但我无法找到问题所在。
第一个是:
vpc_subnet_id: subnet-29e63245
第二个是:
public function academics ($id,$problem_solving , $math_understanding, $cs_understanding , $math_useful , $cs_useful, $math_ava, $cs_ava, $assigment_start, $assigment_submit, $travel_time, $stress,$assigment_when, $full_part, $pair_programming, $attending_class, $attending_labs,$attending_tutorials, $extra_reading, $p_progamming, $q_cs, $q_maths, $procrastinating_assigments, $procrastinating_studying){
try{
$stmt = $this->db->prepare("UPDATE student_data SET problem_solving=:problemS, math_understanding=:math_U, cs_understanding=: cs_u, math_useful =:m, cs_useful=:cs_u, math_ava=:ma, cs_ava=:ca, assigment_start=:ass_st, assigment_submit=:assigment_submit, travel_time =:travel_time, stress=: stress, assigment_when =:assigment_when, full_part =:full_part, pair_programming=: pair_programming, attending_class=: attending_class, attending_labs=: attending_labs, attending_tutorials =:attending_tutorials, extra_reading =:extra_reading, p_progamming=: p_progamming, q_cs=: q_cs, q_maths=: q_maths, procrastinating_assigments=:procrastinating_assigments, procrastinating_studying=:procrastinating_studying WHERE user_id=:uid");

$stmt->execute();
} catch(PDOException $e)
{
echo $e->getMessage();
}
}
答案 0 :(得分:4)
好的,这对于评论来说太长了(没有双关语意图在那个"长"顺便说一句)。
如果那些不错别字(我希望他们不是),那么你有很多在冒号后面有空格的绑定。
您需要删除它们的空格,并将MySQL保留字包裹在LONG
的刻度中,或者将其重命名为保留字以外的其他内容。
即
SET `long`=:long, ...

&#34;我不知道php的空间数,认为它忽略了它们就像C / C ++一样,现在可以使用了。谢谢大家!! - bandos&#34;
