Make a Link Use Post Instead of Get

Make a link use POST instead of GET

You create a form with hidden inputs that hold the values to be posted, set the action of the form to the destination url, and the form method to post. Then, when your link is clicked, trigger a JS function that submits the form.

See here, for an example. This example uses pure JavaScript, with no jQuery — you could choose this if you don't want to install anything more than you already have.

<form name="myform" action="handle-data.php" method="post">
  <label for="query">Search:</label>
  <input type="text" name="query" id="query"/>
  <button>Search</button>
</form>

<script>
var button = document.querySelector('form[name="myform"] > button');
button.addEventListener(function() {
  document.querySelector("form[name="myform"]").submit();
});
</script>

hyperlink a href using POST Method instead of GET method

The post method can only be used by form data if called by html.

So the only solution would be to make a form and hide the inputs which you want to post, and submit the post to the url you want to.

Making href (anchor tag) request POST instead of GET?

Using jQuery it is very simple, assuming the URL you wish to post to is on the same server or has implemented CORS

$(function() {
  $("#employeeLink").on("click",function(e) {
    e.preventDefault(); // cancel the link itself
    $.post(this.href,function(data) {
      $("#someContainer").html(data);
    });
  });
});

If you insist on using frames which I strongly discourage, have a form and submit it with the link

<form action="employee.action" method="post" target="myFrame" id="myForm"></form>

and use (in plain JS)

 window.addEventListener("load",function() {
   document.getElementById("employeeLink").addEventListener("click",function(e) {
     e.preventDefault(); // cancel the link
     document.getElementById("myForm").submit(); // but make sure nothing has name or ID="submit"
   });
 });

Without a form we need to make one

 window.addEventListener("load",function() {
   document.getElementById("employeeLink").addEventListener("click",function(e) {
     e.preventDefault(); // cancel the actual link
     var myForm = document.createElement("form");
     myForm.action=this.href;// the href of the link
     myForm.target="myFrame";
     myForm.method="POST";
     myForm.submit();
   });
 });

PHP link with post instead of get

Most email clients do not support form submissions or any form of Javascript. And you should always assume that people block scripts/images from emails by default. Clicking a link in an email will usually open the user's web browser and redirect them to the page - this way you can attach a query string with ?foo=bar and access these parameters via $_GET.

If you absolutely must retrieve these parameters in $_POST, for whatever reason, you could redirect the user to a form that auto-submits as POST via Javascript (and pre-fill some hidden inputs to have your parameters passed through).

REST API using POST instead of GET

You can't use the API using POST or GET if they are not build to call using these methods separetly. Like if your API say

/service/function?param1=value1¶m2=value2

is accessed by using GET method. Then you can not call it using POST method if it is not specified as POST method by its creator. If you do that you may got 405 Method not allowed status.

Generally in POST method you need to send the content in body with specified format which is described in content-type header for ex. application/json for json data.

And after that the request body gets deserialized at server end. So you need to pass the serialized data from the client and it is decided by the service developer.

But in general terms GET is used when server returns some data to the client and have not any impact on server whereas POST is used to create some resource on server. So generally it should not be same.

How do I make a link use POST method in Yii?

Try this:

<?= Html::a('submit', Url::to(['site/index']), ['data-method' => 'POST']) ?>

Is there a way to make g:link calls POST instead of GET?

1.My suggestion is to use Ajax before the g:link it self handels the call to the action and controller

like:

<g:link class="btn btn-success"  id="class.id" onclick='UsingPost();'>SOME LABLE HERE </g:link>
<script type='text/javascript'>
function UsingPost(){
    jQuery.ajax({
        type:'POST',
        data:{"model":${pleaseUseTheModelyouHaveLoaded}"}, 
        url:'${createLink(action: 'save')}',
        success:function(data,textStatus){
        jQuery('#success').html(data);},
        error:function(XMLHttpRequest,textStatus,errorThrown){}
        });
}
</script>

When do you use POST and when do you use GET?

Use POST for destructive actions such as creation (I'm aware of the irony), editing, and deletion, because you can't hit a POST action in the address bar of your browser. Use GET when it's safe to allow a person to call an action. So a URL like:

http://myblog.org/admin/posts/delete/357

Should bring you to a confirmation page, rather than simply deleting the item. It's far easier to avoid accidents this way.

POST is also more secure than GET, because you aren't sticking information into a URL. And so using GET as the method for an HTML form that collects a password or other sensitive information is not the best idea.

One final note: POST can transmit a larger amount of information than GET. 'POST' has no size restrictions for transmitted data, whilst 'GET' is limited to 2048 characters.

POST from an A tag

There is no way to POST an a element using only HTML.

As can be seen from this DTD fragment (HTML 4.01 spec):

<!ELEMENT A - - (%inline;)* -(A)       -- anchor -->
<!ATTLIST A
  %attrs;                              -- %coreattrs, %i18n, %events --
  charset     %Charset;      #IMPLIED  -- char encoding of linked resource --
  type        %ContentType;  #IMPLIED  -- advisory content type --
  name        CDATA          #IMPLIED  -- named link end --
  href        %URI;          #IMPLIED  -- URI for linked resource --
  hreflang    %LanguageCode; #IMPLIED  -- language code --
  rel         %LinkTypes;    #IMPLIED  -- forward link types --
  rev         %LinkTypes;    #IMPLIED  -- reverse link types --
  accesskey   %Character;    #IMPLIED  -- accessibility key character --
  shape       %Shape;        rect      -- for use with client-side image maps --
  coords      %Coords;       #IMPLIED  -- for use with client-side image maps --
  tabindex    NUMBER         #IMPLIED  -- position in tabbing order --
  onfocus     %Script;       #IMPLIED  -- the element got the focus --
  onblur      %Script;       #IMPLIED  -- the element lost the focus --
  >

There is no attribute that controls whether to use POST or GET with an a element.

You have to script it, if you want to abuse the semantics.
