php grabs link from html option value to Post into Email - php

I have a online e form system, where a user has the option to send a form link to a colleague. The form contains a dropdown of all the forms on the page which contain a link. They then go on to enter the to and from fields.
Email sends but i cant seem to grab the link from the option value.
Form:
<select name="forms" autofocus style="width:54%">
<option> Select a form</option>
<option value="Form1">
Form1</option>
<option value="Form2">
Form2</option>
</select>
(I have not included the whole form just the part i cant get the links for)
How can i use PHP to post the link?
Thanks for any help you can give.
I am not trying to redirect the user. I want to be able to grab a link (Via PHP) depending on what the user selects.

Can you not just set the value of the option to be the URL rather than putting the link in the text part of it?
<select name="forms" autofocus style="width:54%">
<option> Select a form</option>
<option value="Form1.html">
Form1</option>
<option value="Form2.html">
Form2</option>
</select>

you can try this one:
<select name="forms" autofocus style="width:54%" onchange="location = this.options[this.selectedIndex].value;">
<option> Select a form</option>
<option value="Form1">
Form1</option>
<option value="Form2">
Form2</option>
</select>

I think this might work
Include this Javascript to get URL on the currentf form.
<script type="text/javascript">
currentUrl=window.location.href ;
</script>
Recieve it in PHP
<?php
echo "currentUrl: ".$_GET['currentUrl']."<br>";
?>
Alternatively, just get current url in php
$_SERVER['REQUEST_URI']

Try something like this php side:
if $_POST['forms']=='Form1' {$link="full/url/for/Form1.html";}
if $_POST['forms']=='Form2' {$link="full/url/for/Form2.html";}
//send your email here with the value of $link
Besides, you don't need any <a href...> in your html.
<select name="forms" autofocus style="width:54%" method="post">
<option> Select a form</option>
<option value="Form1">Form1</option>
<option value="Form2">Form2</option>
</select>
(or check for $_GET['forms'] instead of $_POSTdepending of the chosen method in your html form).

Submit a html form without submit button [duplicate]

I am creating a page in JSP where I have a dropdown list and once the user selects a value he has to click on the go button and then the value is sent to the Servlet.
</select>
<input type="submit" name="GO" value="Go"/>
How do I make it so that it does it on change? E.g. when the user selects John all his details are retrived from the DB and displayed. I want the system to do it without having to click the go button.
Just ask assistance of JavaScript.
<select onchange="this.form.submit()">
...
</select>

HTML dog - JavaScript tutorial
Simple JavaScript will do -
<form action="myservlet.do" method="POST">
<select name="myselect" id="myselect" onchange="this.form.submit()">
<option value="1">One</option>
<option value="2">Two</option>
<option value="3">Three</option>
<option value="4">Four</option>
</select>
</form>
Here is a link for a good javascript tutorial.
other than using this.form.submit() you also can submiting by id or name.
example i have form like this : <form action="" name="PostName" id="PostID">
By Name : <select onchange="PostName.submit()">
By Id : <select onchange="PostID.submit()">
To those in the answer above. It's definitely JavaScript. It's just inline.
BTW the jQuery equivalent if you want to apply to all selects:
$('form select').on('change', function(){
$(this).closest('form').submit();
});

PHP associate form fields with other fields

I have a form that will be used for quoting items. The user will be able to add blocks of fields to the form which I have working at the moment. Consider the code below
<div class="fields">
<select name="landscaping[]">
<option value="1">Rocks</option>
<option value="2">Other Rocks</option>
</select>
<select name="veneer[]">
<option value="1">Veneer Rocks</option>
<option value="2">Other Veneer Rocks</option>
</select>
<input type="text" name="quantity[]">
</div>
The problem is the user may select either veneer or landscaping but not both but no matter what there will be a quantity associated with the choice. And likely an additional parameter. I need a way to associate quantity with veneer or landscaping in each instance of this section.
Since you are using javascript to hide one of the elements at a time, I would also include a hidden field which holds the value of the select field which you want to grab the value from. You could also just look for the one which has a value, but since they can probably each have a value, it's safer to send a value which tells you for sure which field you should pull from.
<div class="fields">
<select name="landscaping[]">
<option value="1">Rocks</option>
<option value="2">Other Rocks</option>
</select>
<select name="veneer[]">
<option value="1">Veneer Rocks</option>
<option value="2">Other Veneer Rocks</option>
</select>
<input type="text" name="quantity[]">
<!-- This value should change depending on which one is currently visible -->
<input type="hidden" name="selectedField" value="landscaping">
</div>
Then in your form processing page use something like the following:
$selection = $_POST[$_POST['selectedField']];
This will pull the value of your selectedField post dynamically and use it to then grab the correct select list. Using this method can be risky though... Make sure that you sanitize your POST data!

Is there something like readonly property for a dropdown?

My form contains a radio-button & a drop-down. So depending upon the selected value of radio button i need to enable/disable the drop-down.
I am doing this:
<select name="bas_type" id="bas_type" disabled="disabled">
<option value="Monthly">Monthly</option>
<option value="Quarterly">Quarterly</option>
<option value="Annualy">Annualy</option>
</select>
But i want to get drop-down value as empty in $_POST if form is disabled..
So this won't work. Please any suggestions..
Simply add a hidden field with the value you want to receive when the control is disabled and the same name as the dropdown. Be sure to place it before the dropdown in the HTML:
<input type="hidden" name="bas_type" value="" />
<select name="bas_type" id="bas_type" disabled="disabled">
<option value="Monthly">Monthly</option>
<option value="Quarterly">Quarterly</option>
<option value="Annualy">Annualy</option>
</select>
Of course you shouldn't really have to do this, since in PHP you should be receiving incoming parameters with at least a helper function like
function param($name, $default = null) {
return isset($_REQUEST[$name]) ? $_REQUEST[$name] : $default;
}
Don't rely on data you get from form. What you should actually do is check serverside if radiobutton is active or not, and depending on that ignore or accept value from dropbox.
Set the value in the form to "" and that should do the trick:
<option value="">Annualy</option>
or use a space like this (not sure which will work better for you, haven't tried to do it):
<option value=" ">Annualy</option>
Edit: The data contained in the value="something" is the actual data that is passed to the URL via a get. Hence, if you blank it out, the data won't get passed.

2 select boxes with same id's but one hidden

I've 2 select boxes with same id's as well as names but at a time only one is shown.
But when form is posted i do not get the exact value.It only displays the first value from the dropdown.
Following is a sample code of the same.
<?php
var_dump($_POST)
?>
<form method="POST" action="">
<select name="test" id="test">
<option value="0">0</option>
<option value="1">1</option>
<option value="2">2</option>
<option value="3">3</option>
</select>
<select name="test" id="test" style="display:none" >
<option value="0">0</option>
<option value="1">1</option>
<option value="2">2</option>
<option value="3">3</option>
</select>
<input type="submit" value="Add"/>
</form>
I even tried surrounding the select box with a div and then hidding it.
Not sure why you have two select's with the same name, but when you hide one you also need to disable it too (disabled="disabled").
As per HTML specification, disabled fields are not submitted so you should have your true value posted from the select that isn't disabled.
Presumably you're using some javascript to switch which select is displayed?
If that's the case, then start off with
<select name="test" id="test"></select>
<select name="test_dummy" id="test_dummy" style="display:none" ></select>
And whichever code changes the style attribute will also have to change the name and id attributes
Even when one of these is hidden at every point, they should have different names in the markup so you can identify which one is which.
Otherwise it'll pass only the last element's (in the markup) value through the form (no matter if it's hidden via CSS or not).
I'm not quite sure why your hiding/showing only one of these at a time anyway. It'd likely be better if you replaced the <option>'s inside the select to the new ones, instead of using show/hide.
You would have to have different id's and in your code conditionally check which select box value is visible fetch it's value.
When you submit a form, the POST data contains data basing on the attribute name. If they have the same name, the value of the second select overwrites the value chosen from the first one. Even if you hide it in the page.
If you want to have just the value of the first select, you should disable the second one, by adding disabled="disabled" or by changing its name.

How to use PHP to get the *idex* of the selected combobox item, not its text?

If I have a combobBox with values red/white/blue and the users chooses blue then I want my form action php page to use the value 2, not `blue. I hope you see what I mean.
Is there any easy way to do that?
<form action='phpPage.php' name='bsForm' method='POST'>
<select name='TheColor' onSelect="bsForm.submit()">
<option value='0'>red</option>
<option value='1'>white</option>
<option value='2'>blue</option>
</select>
</form>
If your form looks anything like that, then your phpPage should easily be able to get the value 2 from $_POST['TheColor']
You do this by constructing your form appropriately and supplying a value attribute:
<option value="2">blue</option>
