我的PHP代码有问题，我在我的PHP While循环中放了一个AJAX来提交表单。但是当我按下输入时点击提交。查询插入了很多行。我希望在我的数据库中只插入一行。
我在while循环中的代码是：
$POST_ID = $GetData["POST_ID"];
<div class="col-lg-12 col-md-12 col-sm-12 col-xs-12" style="margin: 0; padding: 0; margin-top: 15px;">
<form action="profile/post.validation.php" method="POST" id="frmPostingComment-'.$POST_ID.'">
<input type="hidden" id="GET_FLAG" name="GET_FLAG" value="POST_COMMENT">
<input type="hidden" id="ENTITY_SOURCE" name="ENTITY_SOURCE" value="'.$ENTITY_SOURCE.'">
<input type="hidden" id="PARENT_POST_ID" name="PARENT_POST_ID" value="'.$POST_ID.'">
<input type="hidden" id="PARENT_ID" name="PARENT_ID" value="'.$GetData['MAIN_ID'].'">
<input type="hidden" id="FULL_NM" name="FULL_NM" value="'.$vsFULL_NM_ACTV.'">
<input type="hidden" id="USER_ID" name="USER_ID" value="'.$vnUSER_ID_ACTV.'">
<textarea id="POSTING_COMMENT-'.$POST_ID.'" name="POSTING" class="form-control" style="border: 1px solid #ebebeb; resize: none; height: 40px;" placeholder="Write Comment"></textarea>
</form>
</div>
</div>
</div>
<script>
$("#POSTING_COMMENT-'.$POST_ID.'").keydown(function(event) {
if (event.keyCode == 13) {
$(this.form).submit()
$(this).val("");
return false;
}
}).focus(function(){
if(this.value == ""){
this.value = "";
stopRefresh();
}
}).blur(function(){
if(this.value==""){
this.value = "";
startRefresh();
}
});
$("#frmPostingComment-'.$POST_ID.'").submit(function() {
var formData = new FormData(this);
$.ajax({
type: "POST",
url: $(this).attr("action"),
data: formData,
cache: true,
contentType: false,
processData: false,
success: function(data) {
$("#AJAX_POST_WRAPPER").load("profile/ajax.post-timeline.php?GetFLAG=HOME").fadeTo("fast", 1.0);
},
error: function(XMLHttpRequest, textStatus, errorThrown) {
$("#AJAX_POST_WRAPPER").load("profile/ajax.post-timeline.php?GetFLAG=HOME").fadeTo("fast", 1.0);
}
})
$("#POST_CONTENT").val("");
return false;
});
</script>
谢谢Stackoverflow！ ;）
