问题描述
我有一个下面的html标记(这是一个让你知道的基本结构,因为有些人会问我<< form> 标签在哪里。 )
< input type =textname =set_val_1id =set_val_1value =1 />
< input type =textname =set_val_2id =set_val_2value =2/>
< input type =textname =max_risk_idid =max_risk_idvalue =5/>
< input type =submitvalue =Entername =submit_button/>
现在当表单被提交时,我想要有一个代码来检测是否有任何POST出现在格式 set_val _ 。
基于我的问题的算法:
if(isset($ _ POST ['something with the pattern(set_val_)']))
{
$ flag = 1;
$ val_string =;
}
if($ flag == 1)
{
$ max_id = $ _POST ['max_risk_id'];
for($ i = 1; $ i {
if(isset($ _ POST ['set_val _'。$ i]))
{
$ val_string = $ val_string。 $ _ POST [ _ set_val $ I] 。
}
}
}
如何检查发布了一个特定的名称格式?
新的编辑解释了为什么我需要这个
我有多个多选,检查小提琴:
所以,为此,我以这种方式获取多重选择的数据
if(isset($ _ POST ['max_risk_id']))
{
$ max_id = $ _POST ['max_risk_id'];
for($ i = 1; $ i {
$ offer_combo ='';
if(isset($ _ POST ['risk_mitigator_offer _'。$ i])&& isset($ _ POST ['risk_weight _'。$ i]))
{
$ offer_risk = $ _POST [ 'risk_mitigator_offer _' $ I。];
$ risk_weight = $ _POST ['risk_weight _'。$ i];
print_r($ offer_risk);
foreach($ offer_risk as $ fr)
{
$ offer_combo = $ offer_combo。 $ fr。 ;
}
$ offer_combo = trim($ offer_combo,,);
$ mitigator_insert_query =INSERT INTO mt_risk_mitigator
(camp_id,risk_combination,risk_weight)
VALUES('。$ mysql ['camp_id']。'','$ offer_combo','$ risk_weight );
mysql_query($ mitigator_insert_query);
使用和键盘检查功能
pre $ 函数preg_grep_keys($ pattern,$ input,$ flags = 0){
return array_intersect_key($ input,array_flip(preg_grep($ pattern ,array_keys($ input),$ flags)));
if(count(preg_grep_keys('/ set_val_\\d + /',$ _POST))> 0)
{
$ flag = 1;
$ val_string =;
}
I have a following html markup (it's a basic structure to let you know, as some people will ask me where is the <form> tag. Consider it being there.)
<input type="text" name="set_val_1" id="set_val_1" value="1"/> <input type="text" name="set_val_2" id="set_val_2" value="2"/> <input type="text" name="max_risk_id" id="max_risk_id" value="5"/> <input type="submit" value="Enter" name="submit_button"/>
Now when the form will be submitted I want to have a code to detect whether any POST appeared in the format "set_val_".
An algorithm based on my issue:
if(isset($_POST['something with the pattern (set_val_)'])) { $flag = 1; $val_string = ""; } if($flag == 1) { $max_id = $_POST['max_risk_id']; for($i = 1; $i<=$max_id; $i++) { if(isset($_POST['set_val_'.$i])) { $val_string = $val_string. $_POST['set_val_'.$i].","; } } }
How can I check whether a post occurred of a particular name format?
New edit explaining why I need this
I have multiple multiselect, check the fiddle:
http://jsfiddle.net/p0b4j5o8/24/
So for that, I am having the fetching data of the multi-selects in this fashion
if(isset($_POST['max_risk_id'])) { $max_id = $_POST['max_risk_id']; for($i = 1; $i<=$max_id; $i++) { $offer_combo = ''; if(isset($_POST['risk_mitigator_offer_'.$i]) && isset($_POST['risk_weight_'.$i])) { $offer_risk = $_POST['risk_mitigator_offer_'.$i]; $risk_weight = $_POST['risk_weight_'.$i]; print_r($offer_risk); foreach($offer_risk as $fr) { $offer_combo = $offer_combo . $fr . ","; } $offer_combo = trim($offer_combo,","); $mitigator_insert_query = "INSERT INTO mt_risk_mitigator (camp_id , risk_combination, risk_weight) VALUES ('".$mysql['camp_id']."','$offer_combo','$risk_weight')"; mysql_query($mitigator_insert_query); } } }
Use preg_grep with keys checking function
function preg_grep_keys($pattern, $input, $flags = 0) { return array_intersect_key($input, array_flip(preg_grep($pattern, array_keys($input), $flags))); } if(count(preg_grep_keys('/set_val_\d+/', $_POST)) > 0) { $flag = 1; $val_string = ""; }
