<table border = "0" cellpading = "0" cellspacing = "0" align = "center">

<tr>

<td width = "355"</td>

<td width = "160"><font face = arial size ="2" align = "left"> Have you made changes? </font></td>

 

<td width = "100" align = "center" <? echo "<input type='image' src='updatetrolley.bmp' border='0' alt='Add'> <input type='hidden' name='count' value='" . ($i-1) . "'>" ?>

</td>

</tr>

</table>

</form>

First of all, I always use " " on HTML attributes.  Secondly, I know it's not -really- necessary (but it should be) to use the XML-valid tags...<input />, <br />, etc.

Avoid using the short PHP open tag. Don't know if that's causing the problem, but still. And I totally agree with DarkWater.

Nope thats not what causing the problem I originally developed that table in PHP but I then tried it HTML but to no avail.

if it works in FF but not in IE then its not a php problem, it's just one of those annoying things IE doesnt do that it should. You'll need to lookup a different way to display the button image. Like for example do an image tag and then include "onclick='this.form.submit()'" try that out.

Terrible advise. Using javascript would only be a band aid solution.

 

Take out ALL PHP, only work with parsed php, - only the html. (Come on, that is advice from 101 html class).

 

Get rid of tables. What are you using tables for layout? And instead of using <input type="image" /> use <button type="submit" name="submit"></button>. It is styled and manipulated much easier.

just thought id point out that you arnt closing your td open tags, thats whats causing the problems

 

try

 

   <table border = "0" cellpading = "0" cellspacing = "0" align = "center">
   <tr>
   <td width = "355"></td>
   <td width = "160"><font face = arial size ="2" align = "left"> Have you made changes? </font></td> 

   <td width = "100" align = "center"> <? echo "<input type='image' src='updatetrolley.bmp' border='0' alt='Add'> <input type='hidden' name='count' value='" . ($i-1) . "'>" ?>   
   </td>
   </tr>
   </table>
   </form>

oh yeah, you dont need javascript to use a image as a form submit, the reason that firefox is displaying it is because firefix is intuitive and realizes it is eant to be closed so displays it asif it were closed

You can say that it's not what you would do, but if you're gonna call someone out and say they're flat out wrong, you need to have a good reason.

[mark110384]

Thanks blueman378 that sorted it out no end, dumbass error on my part not close the td open tags, wonder why it worked in FireFox though? Anyway thanks to everyones imput.

[blueman378]

no problem, but the reason it works in firefox is because its a better browser, by this i mean its intuitive, it sees the new tags and realizes they left this open accidentially and renders the codument asif it had been closed

[dannyb785]

and renders the codument asif it had been closed

 

but how does it know where to end the tag? Like what if he wanted the cell to display 'style="whatever"', it would probably interpret that as still being in the tag, right?

[blueman378]

i believe it looks for a < because you obviously wouldnt have that inside a tag would you?

Using javascript is not a good solution, because it won't work if people have javascript turned off in their browser. Search engines also don't employ javascript, so any page that requires it won't be accessible. It's better to create a solution that works with javascript off, then if you want, you can add javascript over top in order to provide better functionality.

 

 

As for how browsers decide what to do with invalid code (which includes missing closing tags etc), well each browser figures out what to do in its own way. This is why invalid code usually produces discrepancies between browsers, and why valid code produces less discrepancies between browsers. If the code validates, then the browsers don't have to make guesses as to how they should display it.

 

[dannyb785]

i believe it looks for a < because you obviously wouldnt have that inside a tag would you?

 

 

Your response doesn't make any sense. A tag starts with a < and if there is no > to end it, how can a browser know when to end it? Referring to a < doesn't apply since the entire question is when would a browser know where to insert the >

[haku]

His answer made sense, though I don't know if that is how browsers actually do it or not.

 

Since there isn't likely to be a '<' inside a tag, if it finds one, then it can guess that this is the first character of the opening tag of the next element, and so the last, unfinished element has probably ended.

[blueman378]

thanks haku thats exactly what i meant, although i should point out im only guessing, and it proborably employs other techniques as well this is jsut one that i can see would be obvious
