I'm new to php and need some help.
I have a text box that a user can type in an html color code (ex:#373737). Once they hit the submit button I want find all color codes matching #379BB9 and replacing them with the new color code they typed in the text box. I want to change this entry on all the css files in a folder. What i'm looking for is the php code to make this work. I've found bits and pieces of code but I could make it work. I only put the code here that relates to the button. Thanks for any help you can give.
Here's the original color code: #379BB9
p {
background-color:#373737;
border:1px solid #373737;
padding-top:5px;
padding-bottom:5px;
padding-left:10px;
padding-right:10px;
color:#379BB9;
width:60px;
cursor:pointer;
-moz-border-radius:3px;
border-radius:3px;
text-transform:uppercase;
}
.message {
background-color:#4f4f4f;
border:1px solid #373737;
width:98.5%;
text-align:center;
margin-bottom:30px;
-moz-border-radius:3px;
border-radius:3px;
text-transform:none;
color:#379BB9;
}
.steps {
text-transform:none;
color:#379BB9;
}
div.notinstalled {
color:#f20723;
}
div.installed {
color:#2cb517;
}
#content a:link, #content a:visited {
color:#379BB9;
font-weight:bold;
text-decoration:none;
}
