PHP - Can I Use Request To Add Text To My Page From Url

So I have a database with BLOBs (jpeg images). I also have a handy PHP page to display the image given an image ID. This page works fine, by getting the data, setting the content-type header to "image/jpeg", and echoing the data.

Now here's the rub: I need the page to also display other information, in text / html format (i.e. show image, and below it show time the image was taken and other information also stored in the database. Because the content-type header has been set as "image/jpeg", I can't display this additional content. How can I make this work?

Thanks!

Hi there,

Is it possible to hide text on a page using PHP? For example, hide the word "hello" every time it appears on the page? Or have it display in a different color?

Hi All,

Bit of a strange one but i would like to be able to supply a URL to a page.

This page will always contain an image and the copyright that goes with it for example

http://www.geograph.org.uk/photo/693325

The copyright lies undearneath

I would like to get some php code that would automatically grab the image and copy this to a directory on mt site and also take the creative commons copyright notice as a string ( which i will then display along side the image when i add it to  my site)

How can i do this through php

I know that the word "copyright" only ever appears once on the page ( as part of the bit im trying to grab) so can i use this somehow to grab the whole string?


Basically im being lazy and would like to automate the process of grabbing the image and copywrite without having to download it to my computer first and reload to my server ( as i will be doing this quite a lot)

Any ideas much appreciated
Thanks

I'm normally fairly proficient with PHP, but I haven't done any coding in quite a while, so I'm a little rusty.

I have an entire page of text from which I need to extract a single value. Here is a small portion of the page in question:

Code: [Select]
Total Rank: 128
Total Points: 4,978
Next Rank: 20

For instance, I need to extract the values "128" "4978" and "20" and store them in variables. These values change all the time, so I'm not sure what the best way to go about this is... maybe a regular expression  ? If that's the case, I've never been too good with them, so any help would be appreciated.

First and foremost, I am a PHP novice so, if there's better or more efficient way of doing what I'm trying to do, please feel free to point it out

I came across an old PHP script that was used to crawl a site and check the response code on the pages found. I have modified it to do a duplicate content check. It's using the similar_text function to compare 1 page's content (specified by the user) against the content of each page it finds.

It's a little slow but, its working. The only problem that I'm having is that it stops after about the first 10 links and I can't figure out why.

Any help is greatly appreciated.

Hi,

I want to show part of the text from a page containing my article on my main page. The article resides in a database in mysql. How do I limit the amount of text that is shown without setting up a separate excerpt box for the article. I want to then provide a link so the user can go to another page that displays the entire article. Thanks for any suggestions.

How can I move my intro text shown in step 2 to the same place in step 1?

Hi,

Wonder if someone could help with the problem below. Got a main page that includes a header, footer and a link to a database. I can get the two Includes to work but can't seem to display the database fields in the body of the page. What has me baffled is that it appears to be connecting to the database, (Opening the connection to the database server The connection worked. The link is: Resource id #3) but no text (see below for database text) is appearing on the screen. Yet I'm not getting a "page_not_found" message. I can go to the database in MYSQL console and query it successfully. Read and (hopefully) applied the section Debugging: A Beginner's Guide, but still can't see the problem. Any help greatly appreciated.

I have a dynamic menu (jglidemenu) installed on my site.  It works fine on my HTML pages but on my PHP pages the font formatting from the menu's style sheet isn't working and I haven't been able to figure out why.

Here's a page where the menu is working correctly:

http://www.greenbayeasthighschool.com

and here's a page where the formatting fails:

http://www.greenbayeasthighschool.com/staff_by_lastname.php

This is my first attempt at creating a page with PHP.  Is it not possible to use CSS formatting on a page that includes PHP content?

Thanks in advance for any help.

Hello.  I currently have a web page that allows a user to enter text into a form then select a "Submit Query" button; upon doing this the entered text is saved to a database and displayed for the user on the same page (the page where the form and "Submit Query" button are located).

My question is as follows: I wish the results to be displayed on a new page when the "Submit Query" button is clicked, not displayed on the same page.  Is this achieved through targeting? I am a bit lost at this point on how to achieve this result.

Thank-you in advance for any help.

Hi Everyone

First off I don't know PHP except the includes statement which I use regularly to make the site a little easier to update.

But anyways am having an issue. I am trying to make a standard template page. On a prior site I had it set up this way with the code I will post below and it worked for me but I have tried to implement it on this site and am not having any luck.

Few things on the code below. It was designed for another site. So what I need is as follows. The home page should bring up the default index.txt file. That has the home page info on it. Second the code below has a table in the coding as I required a table on my site so that is in the code but for this site don't need the table. There is also one image in the code. That too is no longer required.

I will just leave these in place that way you can see the code I am working with so you can hopefully correct it to work for me as I am going nuts trying to get this to work.

Also somewhere in the coding it seems maybe there is an open link tag as I did get this to work a little bit but for some reason when it was the TXT file information was also being made to be a link even though the txt file for time being only contains basic text no coding what so ever.

Now what I need is as follows. Default home page TXT file loaded when home page loads. But the link below is what I was using for my site and when this was clicked it would load the TXT file for that page so the example link below would open up a members page that was associated with my message board I was using.

Code: [Select]
<a href="members.php?categories_file=Members">Forum Members Websites</a>
that link would bring up file members.txt which was stored in the text folder

Below is the code that in both cases was and is placed in the main window of the table I am using for layout. Last time this all worked perfectly but this time not sure why it refuses to load the page like it use to.

Can anyways sort this code so it works fine for me.

Thanks!!
Dave
