I want to make a button that starts my php script after I click it. So do I just make 2 separate files and have action post to the php file and then let it start? or is there a better way to do this? Possibly in one document?
Update:
Well, I basically made a script that would do a series of a loops until it's finished. So usually when I visit the page it automatically starts, so I'm making a button to start it only when I need it.
More info: Answer to one of the questions, "starting the script" as in it would only execute the script.
More info: I really don't need to pass any data from the submit form to the php script. I just want my script to run when I hit a button. I just want to know what's the best way to do this.
Having 2 files like you suggested would be the easiest solution.
For instance:
(.. your html ..)
<form action="script.php" method="get">
<input type="submit" value="Run me now!">
</form>
(...)
<?php
echo "Hello world!"; // Your code here
?>
<?php
if (!empty($_GET['act'])) {
echo "Hello world!"; //Your code here
} else {
?>
(.. your html ..)
<form action="index.php" method="get">
<input type="hidden" name="act" value="run">
<input type="submit" value="Run me now!">
</form>
<?php
}
?>
I know this question is 5 years old, but for anybody wondering how to do this without re-rendering the main page. This solution uses the dart editor/scripting language.
You could have an <object> tag that contains a data attribute. Make the <object> 1px by 1px and then use something like dart to dynamically change the <object>'s data attribute which re-renders the data in the 1px by 1px object.
HTML Script:
<object id="external_source" type="text/html" data="" width="1px" height="1px">
</object>
<button id="button1" type="button">Start Script</button>
<script async type="application/dart" src="dartScript.dart"></script>
<script async src="packages/browser/dart.js"></script>
someScript.php:
<?php
echo 'hello world';
?>
dartScript.dart:
import 'dart:html';
InputElement button1;
ObjectElement externalSource;
void main() {
button1 = querySelector('#button1')
..onClick.listen(runExternalSource);
externalSource = querySelector('#external_source');
}
void runExternalSource(Event e) {
externalSource.setAttribute('data', 'someScript.php');
}
So long as you aren't posting any information and you are just looking to run a script, this should work just fine.
Just build the dart script using "pub Build(generate JS)" and then upload the package onto your server.
