javascript - How to Store PHP Session Values from Multiple Click Events in jQuery? -

-

i trying use jquery pass values session variables when buttons clicked on. each button has unique values , need display values both buttons when both clicked.

the problem having 1 set of values (from recent button clicked) translated session variable - if click first button, first values passed session backend fine, clicking second button afterwards results in second values being passed.

my jquery looks this: 

$button_one.click(function(e) {  e.preventdefault();  var var_one = "value1";  var var_two = "value2";  $.post("sessions.php", { 'session_var_one': var_one, 'session_var_two': var_two }); });  $button_two.click(function(e) {  e.preventdefault();  var var_three = "value3";  var var_four = "value4";  $.post("sessions.php", { 'session_var_three': var_three, 'session_var_four': var_four }); });

the sessions.php simple:

<?php   session_start();   $_session['value_one'] = $_post['session_var_one'];  $_session['value_two'] = $_post['session_var_two'];   $_session['value_three'] = $_post['session_var_three'];  $_session['value_four'] = $_post['session_var_four'];  ?>

and have simple page set display session values:

<?php  session_start(); ?> <!doctype html> <html> <body>  <?php   echo '<h5>' . $_session['session_var_one'] . '</h5>';  echo '<h5>' . $_session['session_var_two'] . '</h5>';   echo '<h5>' . $_session['session_var_three'] . '</h5>';  echo '<h5>' . $_session['session_var_four'] . '</h5>';  ?>  </body> </html>

this page displays 2 values of button last clicked on - instead of displaying both sets of values if both buttons clicked on.

i guessing having 2 separate ajax requests, 1 within each click function, may problem here - when button 2 clicked after button one, "forgets" first request , values not recorded.

i have worked around problem sending each of button click values different session php page (i.e. button_one goes sessions_one.php , button_two goes sessions_two.php) prefer not have create new place store session values each button. plan on adding more buttons , seems bad practice have each button have separate home stored values.

how can rewrite ajax requests and/or sessions.php can store of values each button click? thank guidance, i'm new php , ajax in general!

if $_post variable not provided, code put null in corresponding $_session variable. prevent that, check provided before doing so:

<?php  session_start();  if( isset($_post['session_var_one']) ){     $_session['value_one'] = $_post['session_var_one']; } if( isset($_post['session_var_two']) ){     $_session['value_two'] = $_post['session_var_two']; }  if( isset($_post['session_var_three']) ){     $_session['value_three'] = $_post['session_var_three']; } if( isset($_post['session_var_four']) ){     $_session['value_four'] = $_post['session_var_four']; }  ?>

i want check scene image against 2 train images. that, detect features , compute descriptors of both training images. before detecting, computing , matching scene image, delete matches of train1 , train2. because these matches won't facilitate matching of scene image train1 , train2. so, match train1 train2 , vector of matches trainidx , queryidx. how can delete these matches in keypoints-vector , descriptor matrix of train1 , train2? best regards, dwi i have done below: std::vector<cv::keypoint> keypoints[2]; cv::mat descriptor[2]; std::vector< cv::dmatch > matches; /* write code generate keypoints, descriptors , matches here... keypoint[0] -> train image 1 keypoints keypoint[1] -> train image 2 keypoints descriptor[0] -> train image 1 descriptors descriptor[1] -> train image 2 descriptors matches -> matched between train image 1 , 2 */ // logic keep unmatched keypoints , corresponding descriptor
