PHP的回声提交按钮错误

Question

I can't get my css button to submit. the form directs to the correct page, but nothing gets submitted. any ideas?

echo "<form action=\"submit_something.php\" id=\"submit_x\" method=\"post\">
<input type=\"hidden\" name=\"submit_value\" value\"10\"/><div id=\"button\">
<a href=\"javascript:;\"onclick=\"javascript:document.getElementById('submit_something').submit()\">buttonvalue</a>
</div></div></form>"

update2:

echo "<form action=\"submit_something.php\" id=\"submit_x\" method=\"post\">
<input type=\"hidden\" name=\"submit_value\" value\"10\"/><div id=\"button\">
<a href=\"javascript:;\"onclick=\"javascript:document.getElementById('submit_x').submit()\">buttonvalue</a>
</div></div></form>"

update3: I tried this instead: css:

#btn {font-weight:bold}

html:

<form action="submit_something.php" id="submit_x" method="post">
  <input type="submit" value="button" id="#btn">
</form>

The button doesn't get styled. I tried differentcss parameters, but the submit button doesn't get styled. Any ideas?

Answer 1

You're attempting to submit an element with the ID submit_something , but your form actually has the ID submit_x , so the form won't submit. Also, you shouldn't include javascript: into event handler code like onclick ; this is only needed when you want to execute Javascript code in something like a href .

I don't recommend submitting your form using Javascript by the way, avoid it if you can. Using basic HTML functions like submit buttons where possible can prevent a lot of trouble, for example with usability.

Answer 2

Use the input type of image instead, or style your submit button, instead of this unmaintainable nastiness you have now.

<input type="image" src="myimage.png" />

The image input behaves the same way as a regular submit button.

Or, you can style an actual submit button appropriately, with most of the same styles as your anchor currently. For more info, see http://www.456bereastreet.com/lab/styling-form-controls-revisited/submit-button/

Answer 3

use

<input type="submit" value="button" id="btn">

instead of

<input type="submit" value="button" id="#btn">

to apply the style with id btn.

CSS

#btn {font-weight:bold}

and your php to print the form

echo "<form action=\"submit_something.php\" id=\"submit_x\" method=\"post\">
<input type=\"hidden\" name=\"submit_value\" value=\"10\"/><div id=\"button\">
<a href='' onclick=\"document.getElementById('submit_x').submit();return false;\">buttonvalue</a>
</div></div></form>";
