Send value of submit button when form gets posted

Question

I have a list of names and some buttons with product names  When one of the buttons is clicked the information of the list is sent to a PHP script  but I can t hit the submit button to send its value  How is it done  I boiled my code down to the following   The sending page    lt html gt   lt form action  buy php  method  post  gt       lt select name  name  gt           lt option gt John lt  option gt           lt option gt Henry lt  option gt       lt select gt       lt input id  submit  type  submit  name    Tea     value    Tea  gt       lt input id  submit  type  submit  name    Coffee  value    Coffee  gt   lt  form gt   lt  html gt    The receiving page  buy php   lt  php      name     POST  name         purchase     POST  submit          here some database magic happens   gt    Everything except sending the submit button value works flawlessly

You could use something like this to give your button a value:

<?php
if (isset($_POST['submit'])) {
  $aSubmitVal = array_keys($_POST['submit'])[0];
  echo 'The button value is: ' . $aSubmitVal;
}
?>
<form action="/" method="post">
  <input id="someId" type="submit" name="submit[SomeValue]" value="Button name">
</form>

This will give you the string "SomeValue" as a result

The button names are not submit  so the php   POST  submit   value is not set  As in isset   POST  submit    evaluates to false    lt html gt   lt form action    method  post  gt       lt input type  hidden  name  action  value  submit    gt       lt select name  name  gt           lt option gt John lt  option gt           lt option gt Henry lt  option gt       lt select gt   lt  --  make sure all html elements that have an ID are unique and name the buttons submit  -- gt       lt input id  tea-submit  type  submit  name  submit  value  Tea  gt       lt input id  coffee-submit  type  submit  name  submit  value  Coffee  gt   lt  form gt   lt  html gt    lt  php if  isset   POST  action           echo   lt br   gt The       POST  submit       submit button was pressed lt br   gt        gt

The initial post mentioned buttons  You can also replace the input tags with buttons    lt button type  submit  name  product  value  Tea  gt Tea lt  button gt   lt button type  submit  name  product  value  Coffee  gt Coffee lt  button gt    The name and value attributes are required to submit the value when the form is submitted  the id attribute is not necessary in this case   The attribute type submit specifies that clicking on this button causes the form to be submitted   When the server is handling the submitted form    POST  product   will contain the value  Tea  or  Coffee  depending on which button was clicked   If you want you can also require the user to confirm before submitting the form  useful when you are implementing a delete button for example     lt button type  submit  name  product  value  Tea  onclick  return confirm  Are you sure you want tea      gt Tea lt  button gt   lt button type  submit  name  product  value  Coffee  onclick  return confirm  Are you sure you want coffee      gt Coffee lt  button gt

You can maintain your html as it is but use this php code   lt  php      name     POST  name         purchase1     POST  Tea         purchase2    POST  Coffee      gt

Use this instead    lt input id  tea-submit  type  submit  name    submit     value    Tea  gt   lt input id  coffee-submit  type  submit  name    submit  value    Coffee  gt

Like the others said  you probably missunderstood the idea of a unique id  All I have to add is  that I do not like the idea of using  value  as the identifying property here  as it may change over time  i e  if you want to provide multiple languages     lt input id  submit tea     type  submit  name    submit tea     value    Tea    gt   lt input id  submit coffee  type  submit  name    submit coffee  value    Coffee    gt    and in your php script  if  array key exists   submit tea     POST            handle tea   if  array key exists   submit coffee     POST            handle coffee     Additionally  you can add something like if   POST       SERVER   REQUEST METHOD      if you want to check if data was acctually posted

To start  using the same ID twice is not a good idea  ID s should be unique  if you need to style elements you should use a class to apply CSS instead   At last  you defined the name of your submit button as Tea and Coffee  but in your PHP you are using submit as index  your index should have been   POST  Tea   for example  that would require you to check for it being set as it only sends one   you can do that with isset     Buy anyway   user4035 just beat me to it   his code will  fix  this for you
